Product Overview
The Siemens 6EP1931-2EC31 is a SITOP DC UPS module for maintaining a 24 V DC supply during an interruption to the upstream power source. It accepts a 24 V DC input and provides an output rated at 15 A. When paired with a battery module, it switches to buffered operation so connected control equipment can continue receiving power; buffering time depends on the battery and load.
This version includes a serial PC interface. LEDs and potential-free contacts indicate operating, buffering and alarm states, giving a control system clear information about the DC supply. Its adjustable buffer activation threshold provides a way to define when the module changes from normal to battery-backed operation.
