Siemens 6EP1933-2EC41 DIN Rail DC Power Supply

Siemens SITOP UPS500S 6EP1933-2EC41 is a maintenance-free DIN-rail UPS module that provides a reliable 24 V DC back-up for industrial control circuits. It delivers 24 V DC at up to 15 A (360 W) on the output and includes a USB interface for configuration and monitoring. The unit is powered from a 24 V DC SITOP network with an input range of 22 to 29 V and mounts on a standard DIN rail (DIN EN 60715/EN 50022) with compact dimensions of 120 x 125 x 125 mm and a weight of about 1 kg. It features energy storage of 2.5 kW·s (2.5 kWs) to bridge short interruptions and offers electronic overload and short-circuit protection with automatic restart. Efficiency is rated around 97.5% at rated load, helping minimize energy loss in continuous operation. Enclosures with IP20 protection and ambient operating range 0 to +60 °C make it suitable for indoor automation environments. The UPS500S is marketed as a basic unit with USB interface, intended for applications such as protecting PLCs, sensors, and actuators from power dips or momentary outages, ensuring continuity of critical digital and analog circuits in industrial processes.
