Siemens 6EP1336-2BA10 SITOP PSU100S 24V DC 20A 480W Power Supply

The Siemens 6EP1336-2BA10 SITOP PSU100S is a stabilized DIN-rail power supply that converts 120/230 V AC input into a regulated 24 V DC output rated 20 A, delivering 480 W typical active power at 90% efficiency. Output voltage is adjustable from 24 to 28 V via potentiometer, and it carries a signal relay contact for 24 V OK status.

Selection Notes

20 A at 24 V DC (480 W) sizes this unit for a mid-size control cabinet feeding several PLC racks, remote I/O, and 24 V field devices from one supply rather than splitting the load across smaller units - the output can also parallel with a second identical unit to raise available current further. Auto-ranging 120/230 V AC input means no manual voltage selection when the same design ships to different line voltages. Derating starts above 45 degrees C ambient at 5%/K, so confirm cabinet ventilation before running near the 20 A rated current in warm enclosures.

Applications

Central 24 V DC bus supply for control cabinets running SIMATIC PLCs, remote I/O, sensors, and DC contactor coils where combined load approaches or exceeds 10-15 A.
