Siemens 6EP1931-2EC31 Power Supply

Siemens SITOP DC UPS module 24 V/15 A, 6EP1931-2EC31, is a DIN-rail mounted uninterruptible power supply for 24 V DC control circuits. It accepts a DC input in the 22–29 V range and delivers a stable 24 V DC output rated up to 15 A (about 360 W) to keep critical loads powered during short outages. A serial interface enables communication with PLCs and other controllers for status reporting and remote control. The module is housed in an IP20 enclosure and is designed for installation on standard DIN rails, fitting into Siemens SITOP power architectures in industrial cabinets. Input is typically 24 V DC (up to ~16 A), with the unit providing uninterrupted power to loads such as PLCs, HMI panels, sensors, and small actuators in machines, packaging lines, and other automation equipment where continuous 24 V power is essential.
