- Description
The Siemens 6EP4137-3AB00-1AY0 is a SITOP UPS1600 DC uninterruptible power supply module rated 24 V DC at 40 A with a USB interface. It buffers a 21-29 V DC input against short-circuits and delivers 98.5% efficiency in both normal and battery-buffered operation, with buffering time adjustable from 0.5 to 20 minutes via rotary switch.

Selection Notes
The 40 A rating is the top of the SITOP UPS1600 current range, four times the entry module's output in a housing only 20 mm wider. Efficiency climbs to 98.5% at this rating, the highest of the three current variants, which matters on continuously loaded 24 V buses where every watt of loss becomes cabinet heat. It needs the higher-capacity BAT1600 battery modules to reach its full 120 A peak buffering current, not the smaller lithium or lead-acid packs sized for the 10 A or 20 A units.
