Siemens 6EP4137-3AB00-0AY0 SITOP UPS1600 24V/40A DC UPS Module

The Siemens 6EP4137-3AB00-0AY0 is a SITOP UPS1600 DC uninterruptible power supply module rated for a 24 V DC / 40 A output (120 A peak), buffering the load from an external battery when the 24 V input drops below the adjustable cut-in threshold (21-25 V). Buffering time is set from 0.5 to 20 minutes via a rotary switch, at a typical 98.5% efficiency and 15 W power loss.

Selection Notes

The 40 A rated / 120 A peak output sizes this UPS1600 for a 24 V DC bus feeding several PLCs, drives, or I/O racks through a mains dip, not just a single small controller - check total connected load against the 40 A continuous rating before specifying a smaller SITOP UPS in the same family. The rotary-switch buffering time (0.5-20 min) lets the same module cover both a short ride-through for controlled shutdown and a longer bridge while a generator starts, without reprogramming. Marine classification (ABS, DNV) makes it a fit for shipboard 24 V DC control panels where that approval is a spec requirement.

Applications

Bridges short mains interruptions on 24 V DC control and automation buses: PLC racks, drive control electronics, and instrumentation that must ride through brief supply dips or complete a controlled shutdown before battery reserve runs out.
