[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Please see Figures 1 to 7This utility model provides a technical solution: a multi-channel power control module, including a housing 1, inside which a circuit board 11 is fixed. Six sets of front power output interfaces 12 are fixed on one side of the top of the circuit board 11, and four sets of rear power output interfaces 13 are fixed on the other side of the top of the circuit board 11. A main power input interface 14 is provided at the front end of the circuit board 11, and an LED indicator 15 is provided on one side of the main power input interface 14. The housing 1 has through-holes corresponding to the main power input interface 14 and the LED indicator 15. Inside the housing 1 are a management unit control module, a multi-channel power supply port module, and a multi-channel programmable LED dimming output module. When using the device, firstly, a 24V input is connected to the multi-channel power box device, which is powered via a USB interface. The management unit starts working, activating the 24V and 12V channels. The power status of each channel can be obtained via the LED indicator 15 on the multiple power channels. The front six 24V outputs can provide a maximum rated current of 3A, while the middle four can provide a maximum rated current of 2A. The rear four 12V outputs can provide a maximum rated current of 3A, while the middle two can provide a maximum rated current of 2A. Through the host computer software (connecting the multi-channel power supply box to the computer via an RS485 communication interface), LEDs can be turned on or off, and the PWM frequency and duty cycle can be configured to change LED brightness. Simultaneously, the software can be used to configure the frequency and duty cycle of the additional five PWM signal interfaces for use by other devices.

[0026] In this embodiment, the management unit control module includes a debugging information output interface 16, a debugging interface 17, a power supply indicator and a system operation status indicator 18, a power supply and control command sending interface 19, and a reset button 110. All of these interfaces are located on the side of the circuit board 11. The management unit control module implements the power-on and power-off functions for multiple 24V and 12V power supply channels. It also includes a detection module that acquires the current power-on status of each channel in real time and reports any channel faults to the host computer port. The management unit control module is implemented using a highly integrated MCU. It enables the power-on and power-off functions for multiple 24V and 12V power supply channels. Simultaneously, the detection module can acquire the current power-on status of each channel in real time and report any channel faults to the host computer port. The power-on and power-off sequence of the multiple power supply channels can be adjusted in real time according to the device requirements.

[0027] The management unit control module has an independent external power supply interface: USB-TYPEC provides power to the management unit independently, and commands can be sent via a host computer serial port assistant to realize channel power-on and query functions; an independent debuggable interface 17 supports online debugging and offline module firmware updates; an external serial port can be connected to obtain the management unit's operating status, the power-on status of each 24V channel, and fault reports in real time.

[0028] After the multiple 24V and 12V modules are powered on, the power-on status is indicated in real time by LEDs. The power-on control and status reporting of the channels are realized through the isolation module with the management unit. Moreover, the power supply of LEDs or other status modules is isolated from the power supply of the management unit control module. Even if the power supply of the 24V multi-channel is abnormal, the power supply for indicating the status is not affected.

[0029] This programmable LED dimming output module features an RS485 communication interface, allowing for settings and data acquisition via host computer software. It can also communicate with computers, PLCs, DCS systems, smart meters, and other devices. It offers 6-channel PWM signal output with adjustable frequency and duty cycle, achieving a frequency accuracy of up to 0.1%.

[0030] Multi-channel power supply port module: After the external 24V power supply powers the control box, the 24V and 12V multi-channel power supply channels are configured with different specifications of overload protection measures according to the load requirements of the equipment. After normal power-on under the control of the management unit control module, the corresponding channel LED on the front panel lights up, which can intuitively show whether the current channel is powered on normally. High-power low internal resistance MOSFETs are connected in series between the 24V power supply and each channel. Under the control of the management unit control module, the high-power load is powered normally, reducing the overall loss of the machine.

[0031] In this embodiment, the multi-channel programmable LED dimming output module includes one LED interface 111, an RS485 communication interface 112, five extended PWM signal output interfaces 113, and a backup main power input interface 114. All of these interfaces are mounted on the circuit board 11. The LED dimming output module has an internal power supply and PWM channel connection, allowing direct connection to external LEDs to achieve functions such as LED lighting, flashing, and turning off. Additionally, up to five PWM channel output interfaces can be connected to external signal amplification modules and then to LEDs to achieve similar functions.

[0032] Based on the requirements of multiple 24V and 12V load devices, the management unit can be programmed to control the power-on sequence and interval of each channel. By default, the management unit turns on all 10 power outputs upon power-on and simultaneously checks the output status; if abnormal, it disconnects the power output of the current channel. In addition to powering the management unit, the USB interface allows the computer to send commands to the management unit via the serial communication interface to control the on / off state of the 10 power output ports. Furthermore, the current device firmware version and the output status of the 10 power ports can be obtained by querying commands. The host computer software can control the frequency and duty cycle of 6 PWM signals via the RS485 communication interface, and can also control the on / off state of the 6 signals.

[0033] When using the device, first, connect the 24V input to the multi-channel power supply box. The power supply box is powered via USB interface, and the management unit starts working, activating the 24V and 12V channels. The power status of each channel can be obtained through the LED indicator 15 of the multi-channel power supply. The front row of 6 24V outputs can provide a maximum rated current of 3A, and the middle 4 channels can provide a maximum rated current of 2A. The rear row of 4 12V outputs can provide a maximum rated current of 3A, and the middle 2 channels can provide a maximum rated current of 2A. Through the host computer software configuration (the multi-channel power supply box is connected to the computer via RS485 communication interface), the LEDs can be turned on or off, and the PWM frequency and duty cycle can be configured to change the LED brightness. At the same time, the PWM signal interface of the other 5 channels can be configured through software to configure the PWM frequency and duty cycle for use by other devices.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.

[0035] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
