Siemens 6EP1434-2BA20 SITOP PSU300S 24V/10A 400-500V 3AC Power Supply

The Siemens 6EP1434-2BA20 is a SITOP PSU300S stabilized power supply that converts 400-500 V 3 AC input into a regulated 24 V DC / 10 A output (240 W), with output voltage adjustable 24-28 V via potentiometer. It reaches 91% efficiency, tolerates input dips down to 340 V, and bridges a power failure for at least 7 ms at rated output current.

Selection Notes

The 10 A rated output (12 A up to 45 degC) and 240 W typical output power cover PLC racks, I/O, and 24 V field devices in one unit; step up to a higher-current SITOP model once the panel's continuous 24 V load exceeds this module's derated capacity. Two of these units can be run in parallel to raise available power or add redundancy, and Siemens redundancy, buffer, and selectivity modules from the same PSU300S family extend the base supply without replacing it.

Applications

Central 24 V DC supply for PLCs, remote I/O, sensors, and actuators fed from a 400-500 V 3 AC distribution board, including panels needing ABS/DNV marine classification for shipboard control systems.
