Description:

The Siemens 6EP1931-2DC21 SITOP DC UPS power supply is a DIN-rail‑mounted 24 V DC UPS module designed for industrial back‑up power. It delivers a 24 V DC output at up to 6 A from a 24 V DC input in the 22–29 V range, with an input current of approximately 6 A plus charging current. In the event of a power loss, the unit maintains the 24 V DC output to keep PLCs, HMIs, and other critical control devices powered, making it well suited for control panels, automation lines, and manufacturing facilities. Key specs include IP20 protection, DIN rail mounting, weight around 0.4 kg, and charging currents of 0.2 A or 0.4 A.
