Siemens 6EP4136-3AB00-1AY0 Uninterruptible Power Supply

Siemens 6EP4136-3AB00-1AY0 SITOP UPS1600 is a 24 V DC uninterruptible power supply module designed to back up critical 24 V automation circuits. It accepts a 24 V DC input and delivers a 24 V DC output rated up to 20 A (approximately 480 W), making it suitable for industrial control panels, drives, and other 24 V loads that require short-term power bridging during outages. The unit is part of the SITOP UPS1600 family and is intended to work with SITOP battery modules to provide runtime, with buffering time configurable from 0.5 to 20 minutes (and adjustable via software for extended runtimes). It includes a USB interface for monitoring and configuration, enabling integration with PLCs or HMIs for status, faults, and control signaling. The device supports a programmable charging current up to 4 A, with a rated input current around 25 A at 24 V when charging. This module combines Siemens reliability with easy 24 V system integration, offering a compact, robust backup solution for industrial environments that demand continuous 24 V power to essential equipment.
