Siemens 6EP3436-3SB00-0AX0 SITOP PSU4200 3AC 400/500V 24V/20A Power Supply

The Siemens 6EP3436-3SB00-0AX0 is a SITOP PSU4200 three-phase power supply converting 400/500 V AC input into a stabilized 24 V DC output rated at 20 A, adjustable from 24 to 28 V via potentiometer. It supplies 480 W typical active power at 91% efficiency and includes a DC-OK signal contact for status monitoring.

Selection Notes

The 20 A / 480 W rating scales this PSU4200 for panel-wide 24 V distribution, well above the lower-current SITOP families in this range - pick it when total connected load across multiple DIN-rail devices exceeds what a compact supply can carry. Direct 400/500 V three-phase input removes the need for a separate step-down transformer in 400 V industrial mains, and the integrated DC-OK signal contact allows the PLC to detect an output fault without a separate voltage-monitoring relay. Two units can be operated in parallel to increase available power.

Applications

Suited to control cabinet 24 V bus supply on three-phase 400/500 V industrial installations, multi-drive panels, and applications needing a hardware DC-OK signal for PLC-level power monitoring.
