The Siemens 6EP1931-2FC01 is a SITOP DC-USV-Modul 40, a DC uninterruptible power supply module for 24 V DC systems. It sits between a 24 V DC supply and the load, and switches to a connected battery when the input voltage drops, keeping the 24 V output available. The rating plate gives a 23.5...26 V DC input at up to 40 A, a 24 V DC output at 37 A in mains operation, and up to 40 A in battery operation. Battery connection is via +Bat/-Bat terminals with a maximum 27.3 V charging output, typically 2 A. The module is part of the Siemens SITOP power supply range.
