Description

Technical Field

[0001] The present application relates to the technical field of uninterruptible power supply devices, and in particular to an uninterruptible power supply device and a heat dissipation chassis thereof. Background Art

[0002] A UPS (Uninterruptable Power Supply) is a power supply device containing an energy storage device that provides a stable, reliable, and uninterrupted power supply. It is widely used in industries requiring high power stability, such as telecommunications, finance, industry, and research institutions.

[0003] A conventional UPS consists of a battery pack, an inverter, and a control system. During operation, regardless of whether the grid voltage is normal, the output AC voltage must pass through the inverter, meaning the inverter is always in operation. The battery pack dissipates significant heat during operation, creating a harsh operating environment for the inverter control system and significantly disrupting the system, affecting overall stability and reliability. Conventional UPSs are factory-installed with a fixed structure. If an internal module fails, repair is difficult and inefficient, typically requiring costly replacement of the entire unit.

[0004] Furthermore, when the main utility power fails or experiences an abnormality (e.g., a power outage), the UPS automatically and seamlessly switches to battery operation, converting the required three-phase, four-wire AC power to the load. While the UPS continues to operate, its heat dissipation performance significantly impacts operational stability and safety. To improve heat dissipation, UPS devices are typically larger, making them inconvenient to transport and replace.

[0005] Therefore, it is necessary to provide an uninterruptible power supply device and a heat dissipation chassis thereof to at least partially solve the above problems. Summary of the Invention

[0006] The Summary of the Invention introduces a series of simplified concepts that will be further described in the Detailed Description of the Invention. The Summary of the Invention of this application is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0007] To at least partially solve the above problems, a first aspect of the present application provides a heat dissipation chassis for an uninterruptible power supply device, wherein the uninterruptible power supply device includes a power module, and the heat dissipation chassis includes:

[0008] a housing, wherein the housing is formed with a receiving cavity;

[0009] a mounting plate, the mounting plate extending along the length direction of the heat dissipation chassis and disposed within the accommodating cavity, dividing the accommodating cavity along the height direction of the heat dissipation chassis into an installation space and a wiring space located below the installation space, the mounting plate further being provided with a connector for slidingly connecting the power module; and

[0011] This solution uses mounting plates and partitions to divide the housing into multiple areas, enabling the installation and connection of different modules. This provides a higher level of integration and independence, improving space utilization within the chassis. The power modules are installed using a sliding mechanism, making installation quick and easy.

[0012] Optionally, the connecting member is configured as a slide rail, and the power module is provided with a slider matching the slide rail; or

[0013] The connecting member is configured as a slider, and the power module is provided with a slide rail matching the slider.

[0019] According to this solution, the cooperation between the limit seat and the power module plays a role in installing and positioning the power module.

[0020] Optionally, the heat dissipation chassis further includes a wire tie beam, which is connected to the mounting plate and the housing and is located at the front and rear ends of the mounting plate along the length direction for fixing the adapter cable.

[0021] According to this solution, the cable tie beam and the frame are fixed, and the transferred cables and connectors can be fixed on the cable tie beam, ensuring that the cables are arranged reasonably and facilitating the plugging and unplugging operations when installing and removing the power module.

[0022] Optionally, the housing comprises:

[0024] Cover plates, wherein a plurality of cover plates are respectively arranged on the top, bottom and surrounding of the frame, and the cover plates are detachably connected to the frame to enclose and form the accommodating cavity;

[0025] Wherein, along the length direction, a plurality of groups of second cooling fans are arranged on the cover plate located at the rear end of the shell, and at least one of the remaining cover plates is provided with a cooling hole.

[0027] Optionally, a moving device is provided at the bottom of the frame.

[0029] The heat dissipation chassis according to the first aspect of the present application; and

[0030] A power module is slidably connected to the mounting plate.

[0031] According to this solution, the mounting plates of the power module heat dissipation chassis of the uninterruptible power supply device are slidably connected, and the modular installation and maintenance of the power supply are convenient.

[0032] Optionally, the uninterruptible power supply device further includes a harmonic suppression and filtering module, which is connected to the partition and installed in the second installation area.

[0033] According to this solution, arranging the harmonic suppression and filtering module in the electromagnetic shielding area can reduce electromagnetic interference.

[0034] Optionally, the power module includes:

Under the premise of ensuring heat dissipation performance, the volume of the uninterruptible power supply device can be optimized.

[0040] Other features and advantages of the present application will be described in the following description, and in part will become apparent from the description, or will be understood by practicing the present application.

[0058] The following describes the specific implementation of the embodiment of the present application in detail with reference to the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the embodiment of the present application and is not intended to limit the embodiment of the present application.

[0059] First combine Figures 1 to 7 The illustrated embodiment illustrates the structure of the uninterruptible power supply device 10 and the heat dissipation chassis 100 thereof of the present application.

[0060] refer to Figures 1 to 6 As shown, in this embodiment, the heat dissipation chassis 100 includes a housing 110, a mounting plate 120, and a partition 130. Specifically, the mounting plate 120 may include a connector.

[0061] The housing 110 is formed with a housing cavity. A mounting plate 120 extends along the length direction D1 of the heat dissipation chassis 100 and is disposed within the housing cavity. The mounting plate 120 divides the housing cavity along the height direction D3 of the heat dissipation chassis 100 into an installation space and a wiring space 113 located below the installation space. The mounting plate 120 is also provided with a connector for slidingly connecting the power module 200. The partition 130 is detachably fixedly connected to the mounting plate 120 and divides the installation space along the width direction D2 of the heat dissipation chassis 100 into a first installation area 111 and a second installation area 112. The first installation area 111 is used to install the power module 200, and the second installation area 112 is an electromagnetic shielding area.

[0062] Mounting plate 120 divides the chassis's accommodating cavity into upper and lower mounting spaces and wiring space 113. The mounting spaces are used to install individual modules, while wiring space 113 is used to route wiring harnesses that require magnetic rings or are longer, minimizing interference with the modules. Furthermore, partition 130 divides the mounting space on mounting plate 120 into a first mounting area 111 for connectors and a second mounting area 112 for electromagnetic shielding. Mounting plate 120 and partition 130 divide the accommodating cavity into multiple areas, enabling the installation and connection of different modules, resulting in higher integration and independent functionality, thereby improving space utilization within the chassis. Connectors are slidably connected to mounting plate 120. When a connector needs to be repaired or replaced, it can be easily removed by sliding from mounting plate 120. When the electromagnetic shielding area needs to be repaired or replaced, the side cover 115 of the chassis can be opened to directly access or replace the modules within the electromagnetic shielding area.

[0063] In this embodiment, the uninterruptible power supply 10 may also include a harmonic suppression and filtering module 300. Specifically, the harmonic suppression and filtering module 300 is connected to the partition 130 in the heat dissipation chassis 100 and installed in the second mounting area 112. The harmonic suppression and filtering module 300 is a component of the conversion control system of the uninterruptible power supply 10. To reduce electromagnetic interference, it should be placed in a separate area, namely the second mounting area 112. Specifically, the electromagnetic shielding area can be achieved by providing a shielding layer on the partition 130.

[0064] Specifically, in a preferred example of the present application, Figure 5 and Figure 6 As shown, considering the stability and reliability of the connecting member sliding on the mounting plate 120, the connecting member can be constructed as a slide rail 121 (referring to the slide rail 121 structure itself or the slide rail 121 component formed with the slide rail 121). In this embodiment of the present application, the sliding manner of the connecting member and the mounting plate 120 may include but is not limited to the sliding manner of the slide rail 121 and the slider known to those skilled in the art. Specifically, taking the sliding cooperation of the slide rail 121 and the slider as an example, the connecting member may include the slide rail 121, and the connecting member is provided with a slider that slides with the slide rail 121. It can be understood that the connecting member can also be constructed to include a slider, and correspondingly, the slide rail 121 that slides with the slider is provided on the connecting member.

[0065] In this embodiment of the present application, the form of the slide rail 121 may include various forms known to those skilled in the art, such as a U-shaped (cross-sectional shape of the slide rail 121) track, a T-shaped track, etc. However, in a preferred example of the present application, considering the convenience of sliding fit between the connector and the mounting plate 120, as shown in FIG. Figure 5 as well as Figure 6As shown, the guide bars are detachably connected to the mounting plate 120, and the two guide bars are spaced apart to form a slide rail 121. The guide bars are made of a wear-resistant insulating material. The guide bars reduce friction damage between the power module 200 and the mounting plate 120.

[0066] Furthermore, considering the cost of the mounting plate 120 structure and the simplicity of molding, the slide rail 121 can also be constructed to be integrally molded with the mounting plate 120 .

[0067] In this embodiment of the present application, Figure 3 、 Figure 5 and Figure 6 As shown, further considering the shape and size of the connector, the direction in which the slide rail 121 extends can include along the length direction D1 of the chassis. That is, the power module 200 can be slidably installed along the length direction D1 to the mounting plate 120 of the heat dissipation chassis 100. Specifically, when the connector needs to be repaired or replaced, the cover 115 at the front end 151 of the chassis can be opened to slide the connector out of the accommodating cavity, further improving the efficiency of connector repair / replacement. Optionally, the slide rail 121 extends along the length direction D1.

[0068] In this embodiment, there are two power modules 200, and corresponding connectors corresponding to each power module 200 can be set on the mounting plate 120. Specifically, multiple groups of connectors are distributed in parallel and are roughly parallel to the partition 130. This distribution method, on the one hand, enables any of the multiple groups of connectors to be slid out along the length direction D1 of the chassis / mounting plate 120 and facilitates the maintenance or replacement of the electromagnetic shielding area, thereby improving the reliability of the maintenance or replacement of the multiple groups of connectors; on the other hand, it can also improve the integration between modules, further improve the space utilization inside the chassis, reduce the overall size, and make it more convenient and flexible to use.

[0069] In this embodiment of the present application, Figure 5 and Figure 6 As shown, the mounting plate 120 is further provided with a limit member 122. The limit member 122 is located at the rear end 152 of the mounting plate 120 along the length direction D1 (the end near the rear end 152 of the chassis cover 115). As the connector is slidably installed along the slide rail 121, the connector gradually contacts the limit member 122 and is restrained in place. This limits the sliding position of the connector and ensures the installation and positioning of the power module 200.

[0070] Exemplarily, the power module 200 may further be provided with a positioning portion 123 matching the limiting member 122 : when the power module 200 is slidably connected to the mounting plate 120 , the positioning portion 123 is connected to the limiting member 122 to limit the power module 200 from sliding further along the length direction D1 .

[0071] Specifically, the position limiter 122 can limit the movable end position of the connector, so that the connector is in a position where it can be stably connected and fixed to the chassis, thereby achieving reliable fixation of the connector. In addition, if the slide rail 121 and the slider at the bottom of the connector have poor dimensional compatibility, the limiting effect of the position limiter 122 and the positioning portion 123 can also assist in positioning the connector at one end in the longitudinal direction D1, thereby facilitating the subsequent positioning of the other end, thereby enhancing versatility and ensuring that the power module 200 is stably installed in the first installation area 111.

[0072] In this embodiment of the present application, Figure 5 and Figure 6 As shown, the specific form of the limiting member 122 may include an L-shaped plate. Specifically, the horizontal section of the limiting member 122 is used to fix with the mounting plate 120, and the vertical section is provided with two sets of positioning holes, which are used to cooperate with the positioning portion 123 for positioning. Specifically, the specific form of the positioning portion 123 may include a positioning pin (such as Figure 7 In the embodiment of the present application, in the case of multiple sets of connectors, the limiting members 122 may include multiple sets, each corresponding to each of the multiple sets of connectors. Specifically, the distribution of the multiple sets of limiting members 122 may include a staggered distribution to accommodate the limiting effect of connectors of different sizes.

[0073] Specifically, in this embodiment, the harmonic suppression and filtering module 300 is mounted on the side of the partition 130 away from the connector, that is, on the side of the partition 130 facing one of the side covers 115 along the width direction D2 of the heat dissipation chassis 100. Therefore, if the harmonic suppression and filtering module 300 malfunctions, the side cover 115 of the heat dissipation chassis 100 can be opened to facilitate maintenance, wiring, and replacement of the electromagnetic module. The harmonic suppression and filtering module 300 is fixedly mounted on the surface of the partition 130 facing the second mounting area 112, providing harmonic suppression and filtering functions on both the input and output sides of the uninterruptible power supply 10. A shielding layer is provided on the surface of the partition 130.

[0074] In other embodiments not shown in the present application, with respect to the relative positional relationship between the partition 130 and the connector, taking into account the convenience of maintenance of the harmonic suppression and filtering module 300 on the partition 130, the partition 130 can be located at the head end or tail end of multiple groups of connectors, that is, the front end 151 or the rear end 152 along the length direction D1 of the heat dissipation chassis 100.

[0075] In this embodiment of the present application, Figures 3 to 6As shown, the mounting plate 120 may include a through hole 124. Specifically, a through hole 124 is provided on the mounting plate 120, and the through hole 124 is located near the limiter 122 and close to the partition 130, that is, the through hole 124 is close to the side and rear of the chassis. The present application enables the rear of the chassis to be connected with the wiring space 113 below the mounting plate 120 by arranging the through hole 124 close to the side and rear of the chassis. For example, for some wiring harnesses that require a magnetic ring, they can be placed in the space below the mounting plate 120 to avoid affecting and occupying the space of the connectors above the mounting plate 120, further improving the rationality of the wiring harness and the integration of the spatial layout.

[0076] In this embodiment of the present application, Figures 3 to 6 As shown, the heat dissipation chassis 100 may further include a wire tie beam 141. Specifically, the wire tie beam 141 includes a plurality of wire tie holes.

[0077] The cable tie beam 141 is connected to the mounting plate 120 and the housing 110 and is located at the rear end 152 of the mounting plate 120 along the length direction D1 thereof, and is used to fix the adapter cable. A plurality of cable tie holes are evenly formed on the cable tie beam 141 .

[0078] The transferred wiring harness is fixed on the wire binding beam 141, and the wiring harness is fixed by the harness hole. When installing / removing connectors, the wiring harness can be quickly plugged in and out without being messy, thereby realizing the rapid installation and removal of the power module 200.

[0079] In this embodiment of the present application, Figure 3 As shown, there may be two groups of tie beams 141. Specifically, the two groups of tie beams 141 are respectively disposed at both ends of the partition 130 along the length direction D1, and the tie beam 141 at the end of the partition 130 close to the through hole 124 passes through the through hole 124.

[0080] The wiring harness located above the mounting plate 120 can be routed along the harness hole. The presence of tie beams 141 at both ends of the partition 130 effectively reduces the wiring path and ensures wiring stability. Tie beams 141 near through-hole 124 extend through through-hole 124, providing ample space for wiring harnesses with magnetic rings while maintaining a stable connection to the module above the mounting plate 120.

[0081] In this embodiment of the present application, Figures 1 to 6As shown, the housing 110 of the heat dissipation chassis 100 includes a frame 114 and a cover 115. The frame 114 is constructed in a generally rectangular shape, with multiple cover plates 115 disposed on the top, bottom, and sides of the frame 114. The cover plates 115 are detachably connected to the frame 114 to form a housing cavity. The housing 110 of the heat dissipation chassis 100 is also provided with multiple sets of second cooling fans 116 and heat dissipation holes 117.

[0082] In this embodiment of the present application, Figure 7 As shown, the connecting member may include a housing 210 , a first cooling fan 211 and a pull-out handle 213 .

[0083] The connector can be disposed at the bottom of the housing 210. A first cooling fan 211 is disposed on the housing 210 and is located at a front end 151 of the housing 210 in the longitudinal direction D1 (in this embodiment, the longitudinal direction D1 of the housing 210 coincides with the longitudinal direction D1 of the chassis) to dissipate heat from the components in the connector (specifically, the DC / AC module, AC / DC module, or related control circuits, as described below).

[0084] Specifically, the front end 151 of the housing 210 is opposite to the front end 151 cover 115 of the chassis. A pull-out handle 213 is provided on the housing 210 and is disposed near the first cooling fan 211 .

[0085] The heat dissipation outlet 212 of the power module 200 is located at the rear end 152 in the length direction D1. Figure 7 As shown, heat dissipation outlets 212 are provided at the rear end 152 and the left and right sides of the housing 210. When the connector is dissipating heat, air enters from the first cooling fan 211 and exits at the other end of the connector in the longitudinal direction D1 to dissipate heat from the power module 200 itself.

[0086] Along the length direction D1, a plurality of second cooling fans 116 are provided on the cover plate 115 at the rear end 152 of the housing 110, and at least one of the remaining cover plates 115 is provided with a cooling hole 117. Figure 1 In the illustrated embodiment, a cover plate 115 at the front end 151 of the housing 110 is provided with a plurality of array-distributed air inlet holes 119. Since the connector in this embodiment is slidably mounted along the longitudinal direction D1, the gap between the connector and the chassis also forms a long, strip-shaped channel extending along the longitudinal direction D1. This, combined with the plurality of second cooling fans 116 on the cover plate 115 at the rear end 152 of the heat dissipation chassis 100, allows for ventilation of the front and rear ends 152, thereby better dissipating heat from the connector.

[0087] refer to Figure 1 and Figure 2, heat dissipation holes 117 are provided on the two cover plates 115 that are opposite to each other in the width direction D2, and the heat dissipation holes 117 are provided near the rear end 152 of the housing 110. When heat dissipation holes 117 are provided on the two cover plates 115 on the left and right sides of the heat dissipation chassis 100, it is more conducive to the heat dissipation of the modules inside the first installation area 111 and the second installation area 112. Figure 7 The heat dissipation outlet 212 of the power module 200 is arranged near the rear end 152 , and multiple groups of heat dissipation holes 117 are arranged at the rear end 152 of the housing 110 , which can improve the heat dissipation efficiency of the power module 200 .

[0088] It will be appreciated that when the connector is slidably mounted on the mounting plate 120, the first cooling fan 211 aligns with the front 151 cover plate 115 of the chassis. The connector uses the first cooling fan 211 to allow air to enter the front 151 and exit the rear 152. The chassis also has air entering the front 151 and exiting the rear 152. The two cooling methods align, further improving heat dissipation efficiency and reducing product size while ensuring heat dissipation performance. Experimental data confirms that when the uninterruptible power supply 10 utilizes the heat dissipation chassis 100 according to the present application, the same temperature rise can be achieved with a smaller size than products with equivalent performance.

[0089] In this embodiment, during the operation of the uninterruptible power supply device 10, the heat dissipation process of the heat dissipation chassis 100 is as follows: the first heat dissipation fan 211 (refer to Figure 3 and Figure 7 ) directs air through the cooling holes 117 on the cover 115 at the front 151 of the chassis, dissipating heat from the components within the power module 200 and accelerating the flow of heat and air near the connectors. Simultaneously, a second cooling fan 116 on the cover 115 at the rear 152 of the cooling chassis 100 exhausts hot air from within the chassis, further dissipating heat. The cooling holes 117 on the cover 115 on the left and right sides of the cooling chassis 100 collaborate to dissipate heat, effectively improving the speed and effectiveness of heat dissipation.

[0090] It is understandable that heat dissipation holes 117 may also be provided on the top cover plate 115 and the bottom cover plate 115 of the heat dissipation chassis 100 .

[0091] In this embodiment of the present application, Figure 7 As shown, the housing 210 of the battery module is box-shaped, which can facilitate the removal of the conversion module for maintenance or replacement, and also facilitate the parallel distribution of multiple groups of connectors and partitions 130, with a higher degree of integration. When the connector needs to be removed, it can be assisted by pulling the pull-out handle 213. Figure 3 In the illustrated embodiment, two pull-out handles 213 are provided on each battery module, and the two pull-out handles 213 are spaced apart along the height direction D3.

[0092] When a connector needs to be repaired or replaced, the chassis is opened, the fasteners of the connector are removed, and the corresponding connector is pulled out by sliding the handle 213. The arrangement of the handles 213 near the top and bottom of the housing 210 further improves the stability of the connector removal. Specifically, the handles 213 can be rotated and folded until they fit snugly against the housing 210. When in use, the handles 213 are simply rotated to be perpendicular to the housing 210. This foldable storage structure further improves the integration of the connector.

[0093] In this embodiment of the present application, Figure 3 As shown, the housing 210 may include multiple sets of fastening bolts and two sets of fastening plates. The two sets of fastening plates are disposed at the top and bottom ends of the housing 210 near the first cooling fan 211. Multiple sets of fastening bolts are disposed on the two sets of fastening plates, respectively, for coupling and fastening the box frame 114 and the fastening plates.

[0094] To remove the connector, simply loosen the corresponding fastening bolts. Conversely, to secure the connector, fastening plates are secured to the box frame 114 using fastening bolts. This, combined with the guides and constraints of the connector, allows for stable securement of the connector. Furthermore, four sets of fastening bolts can be provided, each located at the corner of each of the two sets of fastening plates. This coordinated tightening method further enhances the stability and reliability of the connector's securement.

[0095] refer to Figure 2 In the illustrated embodiment, the rear end 152 cover 115 of the heat dissipation chassis 100 may include a battery port 143 and a mains power inlet 145. Specifically, the mains power inlet 145 is located below the battery port 143. In this application, the battery pack is externally located, and the battery pack and power module 200 are connected using a power cable. This approach effectively improves the convenience and flexibility of the uninterruptible power supply 10, making it more convenient to move.

[0096] In this embodiment of the present application, Figures 1 to 5 As shown, the frame 114 may include a moving device 118. Specifically, the moving device 118 is disposed at the bottom of the frame 114 and is used to cooperate with moving the entire heat dissipation chassis 100, thereby further improving the convenience of moving the uninterruptible power supply 10 during use, portability, etc. Furthermore, the moving device 118 may include multiple sets of sliding wheels.

[0097] like Figure 1As shown, the front end 151 of the heat dissipation chassis 100 can include a display and control front panel and a display screen assembly 142. The display and control front panel is located on top of the front end 151 of the cover 115, and the display screen assembly 142 is embedded in the top of the display and control front panel and is tilted relative to the display and control front panel. The display screen assembly 142 can display the operating status and parameters of the uninterruptible power supply 10 and can also perform simple control. The tilting of the display screen assembly 142 relative to the display and control front panel can facilitate user viewing and use, providing a better user experience.

[0098] Through the above technical solution, the uninterruptible power supply device 10 and its heat dissipation chassis 100 provided in the present application divide the interior of the chassis into an installation space and a wiring space 113 through the mounting plate 120, and the partition 130 divides the installation space of the mounting plate 120 into a first installation area 111 and a second installation area 112, thereby realizing modular partitioning, making it easy to plug in and out modules and achieving a higher degree of integration, that is, improving the space utilization rate inside the chassis; at the same time, the connector is slidably arranged on the mounting plate 120 through the connector, and can be quickly and conveniently removed when the connector needs to be repaired or replaced, thereby improving the efficiency and flexibility of repair / replacement, thereby ensuring the reliability of the uninterruptible power supply device 10.

[0099] The uninterruptible power supply device in the embodiment of the present application is an online uninterruptible power supply, and its functional parts mainly include a rectifier (charger), an inverter, a static bypass switch and a manual maintenance bypass switch. The uninterruptible power supply device of the present application realizes its functions by connecting an external large-capacity battery pack.

[0100] In this application, the rectifier and related control circuits are integrated into a rectifier module (AC-DC power module), the inverter, static bypass switch, manual maintenance bypass switch and related control circuits are integrated into an inverter module (DC-AC power module), and the power module mentioned in this application includes a rectifier module and an inverter module.

[0101] Figure 8 The following diagram shows three different working modes (normal mode, battery mode and bypass mode) of the uninterruptible power supply device according to the present application. Figure 8 The working principle of the uninterruptible power supply device in the embodiment of the present application is described.

[0102] Normal working mode: When the main power supply is normal, the uninterruptible power supply device is in normal working mode. On the one hand, it can provide high-quality AC power to the load online through the rectifier and inverter, and on the other hand, it charges the battery through the rectifier and stores energy in the battery.

[0103] Battery operation mode: When the main power is cut off or abnormal, the uninterruptible power supply device can automatically and uninterruptibly switch to battery operation mode. The battery outputs the three-phase four-wire AC power required by the user through the inverter to supply power to the load; when the main power is restored, the uninterruptible power supply device automatically and uninterruptibly returns to normal operation mode.

[0104] Static bypass working mode: There are two bypass working modes, one can automatically restore to normal working mode; the other can return to normal working mode under manual intervention.

[0105] When the inverter overload delay time expires or the inverter is subjected to a large load shock, the UPS will automatically and uninterruptibly switch to the static bypass power supply to supply power to the load. Normal power supply will automatically resume after the UPS returns to normal.

[0106] When the user shuts down the power supply, the mains power fails (or is abnormal) and the battery energy is exhausted, or a serious fault occurs, the inverter shuts down and the UPS remains in bypass mode. To restore normal operation, the user must restart the power supply.
