Description

About the Battery module

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.

Ambient conditions 5

ambient condition For storage, mounting and operation of lead-acid batteries, the relevant DIN/VDE regulations or country-specific regulations (e.g. VDE 0510 Part 2/EN 50272-2) must be observed. You must ensure that the battery site is sufficiently ventilated. Possible sources of ignition must be at least 50 cm away.
ambient temperature: during operation -15 ... +50 °C
ambient temperature: during transport -20 ... +50 °C
ambient temperature: during storage -20 ... +50 °C
relative temporary capacity loss at 20 °C in a month typical 3%

Service life 6

service life of energy storage: typical capacity falls to 80 % of original capacity (according to EUROBAT)
service life of energy storage: at 20 °C typical 4 a
service life of energy storage: at 30 °C typical 2 a
service life of energy storage: at 40 °C typical 1 a
service life of energy storage: at 50 °C typical 0.5 a
note Along with the storage and operating temperature, other factors such as the duration of the storage period and the charge status during storage have a decisive influence on the possible useful life. Batteries should therefore be stored as briefly as possible, always fully charged, and within the temperature range 0 to +20 °C.
