Product Overview

The Siemens SITOP UPS500S basic unit (6EP1933-2EC41) is a maintenance-free uninterruptible power supply module using capacitor energy storage. It accepts a 24 V DC input (22…29 V range) and delivers a 24 V DC output at up to 15 A. The module provides approximately 2.5 kWs of energy, mounts on DIN-rail, and is intended to buffer critical 24 V DC control power during mains supply interruptions. Typical industrial applications include protection of PLCs, I/O modules, sensors, and actuators in automation systems requiring short-term backup.
