Description

The Siemens 6EP1933-2EC41 is a maintenance-free DC UPS module in the SITOP UPS500S series, designed to bridge 24V DC control circuits through power interruptions. It accepts 22–29V DC input, delivers a stable 24V DC output at up to 15A, and holds an adjustable buffer threshold factory-set at 22.5V.

Capacitor-based storage eliminates battery cycles, supplying 2.5 kWs of energy — enough to sustain 15A for 3 seconds or 2A for 38 seconds. It snaps onto a 35mm DIN rail, terminates via screw connections, and reports system status through onboard LEDs, floating relay contacts, and a USB interface. Rated IP20 for panel installation.

Frequently Asked Questions

What buffer duration does the 6EP1933-2EC41 provide at full 15A load?

At 15A, the unit buffers for 3 seconds. Lower loads extend runtime: 10A for 6 s, 5A for 15 s, or 2A for 38 s.

Can the buffer time be extended beyond what the base unit provides?

Yes. The SITOP UPS501S expansion module connects to the 6EP1933-2EC41 to increase available buffering capacity.

Does the 6EP1933-2EC41 require battery replacement or scheduled maintenance?

No. Capacitor-based energy storage eliminates batteries, so no scheduled replacement or maintenance cycles are required.
