Siemens 6EP1332-5BA10 SITOP PSU100C 24V/4A DIN-Rail Power Supply

The Siemens SITOP PSU100C (6EP1332-5BA10) is a stabilized DIN-rail power supply converting 100-230 V AC (or 110-300 V DC) input to a regulated 24 V DC / 4 A output, adjustable 22.2-26.4 V via potentiometer. It reaches 88% efficiency, tolerates a 34 A inrush current, and carries a CE mark plus cULus and EAC approvals in an IP20 enclosure.

Selection Notes

The 100-230 V AC / 110-300 V DC dual-rated input means this unit runs unchanged on either an AC mains feed or a DC control-voltage bus, which matters on panels where a common DC backbone feeds multiple loads. A 4 A / 96 W rating sits at the lower end of the PSU100C range; loads approaching or exceeding that figure need the next current step rather than paralleling units casually, though up to 2 units can be paralleled per the datasheet for redundancy or added capacity. The output remains adjustable 22.2-26.4 V through a potentiometer, useful for compensating voltage drop on long DC field-wiring runs. Marine classification (ABS, DNV) extends its use onto ship and offshore panels beyond standard industrial installations.

Applications

24 V DC control-cabinet power for PLCs, I/O, sensors, and contactor coils on general industrial panels, including marine and offshore installations where ABS/DNV classification is required.
