Uninterrupted power supply

Abstract

The invention discloses an uninterrupted power supply. The uninterrupted power supply comprises a 220 VAC power module and\or a 12 VDC power module, a battery system, a common base and a frame body, the 220 VAC power module and the 12 VDC power module both comprise power monitoring modules and battery accessing modules, and the battery system comprises a battery managing system and a battery pack;the 220 VAC power module, the 12 VDC power module and the battery managing system are all arranged in the frame body, the common base is arranged at one side of the frame body, and the 220 VAC powermodule is provided with a 220 VAC output port, a battery accessing port and a 220 VAC input port; the 12 VDC power module is provided with a 12 VDC output port, a battery accessing port and a 220 VACinput port, the common base is provided with a 12 VDC output port, a 220 VAC output port, a battery accessing port and a 220 VAC input port which correspond to the 220 VAC power module and the 12 VDCpower module, the 220 VAC power module and the 12 VDC power module are arranged on the common base, and the battery accessing ports are connected with the battery system. The uninterrupted power supply can make a system simpler, more reliable and more energy-saving.

Description

technical field [0001] The invention relates to the technical field of data center power supply, in particular to an uninterruptible power supply. Background technique [0002] With the explosive growth of data business demands such as mobile Internet, Internet of Things, and cloud computing, and the rapid development of IT technology, as an important carrier of information, data centers have ushered in a new wave of construction. As the power source for equipment operation, the reliability and efficiency of the power supply also affect the reliability and efficiency of the entire system. [0003] The main equipment in the data center is server equipment, storage equipment, network switching equipment, etc. The servers and storage equipment need to be equipped with switching power supplies for conversion, and the 220VAC or 240VDC voltage will finally be 12VDC voltage level to supply power for their internal motherboards; while switches and other equipment, Due to the large ...

AI Technical Summary

Problems solved by technology

[0004] In the process of realizing the present invention, the inventor found that there are at least the following problems in the prior art: the traditional data center power supply system uses 220V AC UPS power supply or 240V high-voltage DC power supply to supply power to the server, and the output voltage of these two kinds of uninterruptible power supplies should pay more attention to Universality and application breadth are not designed according to the needs of the actual load of the data center. A huge number of switching power supplies for servers have great efficiency loss and waste of funds; switching power supplies for servers only provide 12VDC power supply levels, which cannot be used very well. Supports 220VAC power supply equipment such as network switching, and requires additional wiring, resulting in complex equipment structure
