POWER SUPPLY SYSTEM MODULE

摘要

A power supply system module that includes a first and second AC terminals, positive and negative DC terminals and a housing. An AC-DC converter is connected to the first and second AC terminals, and a DC-DC converter is connected between the AC-DC converter and an internal DC bus. A protection circuit is connected between the internal DC bus and the positive or negative DC terminal. A control device controls the AC-DC converter and/or the DC-DC converter. The AC-DC converter, the DC-DC converter and the control device are provided inside the housing. The power supply system module also includes a backup battery device that has a backup battery connected to the internal DC bus via a battery management system. The backup battery device is provided inside the housing.
