- Description
The Siemens 6EP1935-6ME21 is a SITOP battery module with a 7 Ah maintenance-free lead-acid battery pack rated 24 V DC, sized for the SITOP DC UPS 6 A, 15 A, and 40 A modules. It supplies up to 30 A in buffering mode and 30 A peak, and mounts on a wall via keyhole mounting rather than snapping onto a DIN rail.

Selection Notes
This is the largest battery module in the SITOP family, covering the 6 A, 15 A, and 40 A DC UPS modules where the 3.2 Ah and 2.5 Ah modules only reach up to 15 A. Its 30 A buffering current and peak current are what make the 40 A UPS module usable at full load. Unlike the smaller battery modules, it is wall-mounted rather than DIN-rail snap-on, which should be accounted for in enclosure layout given its 6 kg weight and larger 186 x 168 x 121 mm footprint.
