Siemens 6EP1933-2EC41 Maintenance-Free DC UPS

Siemens 6EP1933-2EC41 is a SITOP UPS500S maintenance-free DC UPS based on capacitor energy storage. The basic unit provides 2.5 kWs stored energy, accepts a 24 V DC input and supplies 24 V DC at up to 15 A. A USB interface supports connection to a PC, while front indicators and signaling contacts communicate operating, buffer and energy-storage states. The IP20 enclosure snaps onto a DIN rail for control-cabinet installation. Siemens classifies this exact article number as PM300: Active Product. System selection should verify load current, required buffer duration, supply range, USB requirements, mounting space and downstream equipment behavior during voltage interruption.
