Siemens 6EP3434-7SB00-3AX0 SITOP PSU6200 24V/10A 3AC Power Supply

The Siemens 6EP3434-7SB00-3AX0 is a SITOP PSU6200 stabilized power supply that converts 3AC 400-500V input to a regulated 24V DC output at up to 10A, with an adjustable 24-28V output range, 95.4% efficiency, and a diagnostics interface for supply and load monitoring. It mounts on a DIN rail, weighs 0.9 kg, and buffers the rated output current for at least 30 ms during a mains dip.

Selection Notes

The 10 A rated output supports 12 A continuously up to 45C before thermal derating, which gives headroom for inrush loads at machine start-up without oversizing the supply. DIP-switch-selectable parallel operation lets two units share load or back each other up on a 24V DC bus, and the diagnostics interface reports a DC-OK contact for controller monitoring without extra wiring.

Applications

Feeds the 24V DC control bus in an automation cabinet - PLC racks, remote I/O stations, relays, and sensor/actuator loops - from a 3-phase 400-500V supply, with the diagnostics contact wired back to a controller input for power-loss monitoring.
