Siemens 6EP1935-6MF01 SITOP Battery Module 24V 12Ah Maintenance-Free DC UPS Module

The Siemens 6EP1935-6MF01 is a SITOP battery module with 24 V/12 Ah maintenance-free sealed lead-acid batteries, built to extend runtime on the SITOP DC UPS modules rated 6 A, 15 A and 40 A. It delivers up to 30 A in buffering mode and up to 30 A peak current, with a 20 A/32 V battery fuse for short-circuit protection and a maximum 3 A charging current.

Selection Notes

This 12 Ah battery pairs with SITOP DC UPS modules across the 6 A, 15 A and 40 A range - verify buffering runtime against the connected UPS module's load rather than this module's 30 A output-current ceiling, which is a maximum, not a guaranteed runtime figure. The 20 A/32 V battery fuse and Class III protection rating fix the safety boundary for the pack itself, and wall or flat-surface keyhole mounting keeps the 9 kg pack out of the UPS module's own footprint. Service life drops from 4 years at 20 degC to 2 years at 30 degC, so ambient temperature at the installation site is the main variable to check before setting replacement intervals.

Applications

Used as the battery back-up stage in SITOP DC UPS installations protecting PLCs, drives and control panels through mains interruptions, where the 6 A, 15 A or 40 A UPS module handles power management and this module supplies the stored 24 V DC energy.
