Siemens 6EP1935-6MD11 SITOP Battery Module 24V/3.2Ah Power Supply Buffer Module
SITOP battery module, 24V/3.2Ah lead-acid, for SITOP DC UPS 6A and 15A modules.
Description
About the Battery module
About the Battery module
The Siemens 6EP1935-6MD11 is a SITOP battery module with a 3.2 Ah maintenance-free lead-acid battery pack rated 24 V DC, sized for the SITOP DC UPS 6 A and 15 A modules. It supplies up to 9.6 A in buffering mode and 15 A peak, and mounts on the same DIN rail as its host UPS module or onto a wall via keyhole mounting.

Selection Notes
Match this 3.2 Ah module to the SITOP DC UPS 6 A or 15 A modules: its 9.6 A buffering current and 15 A peak cover both, whereas the 6 A-only 1.2 Ah module cannot support the 15 A UPS at full load. Step up to the 7 Ah module for the 40 A UPS module or where longer buffering time is required at 15 A. As with the other lead-acid modules in this family, the typical 4-year service life at 20 degC drops sharply at higher ambient temperature, so size the replacement interval to the installation's actual operating temperature.

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. |
