Siemens 6EP3436-8UB00-0AY0 SITOP PSU3800 400-500V 24V/17A Power Supply

The Siemens 6EP3436-8UB00-0AY0 SITOP PSU3800 converts a 400-500 V 3AC input into a stabilized 24 V DC output at 17 A (408 W), optimized for battery-charging profiles. It reaches 94% efficiency, includes an adjustable 24-28 V trim range, and provides a relay contact for remote 24V-OK signaling.

Selection Notes

The 17 A / 408 W rating positions this PSU3800 unit above the lower-current SITOP DIN-rail supplies for loads that need more sustained 24 V current from a three-phase feed. Being optimized for battery charging, its adjustable 24-28 V output and switchable bridging characteristic support a float/boost charging curve that a fixed-voltage sibling cannot provide. The relay contact for 24 V OK gives a hardwired remote-monitoring signal without an add-on module, and the three-phase 400-500 V input matches cabinets already fed from a 3-phase supply rather than single-phase mains.

Applications

Three-phase-fed control cabinets, stand-by battery charging circuits, and machine panels needing more than 400 W at 24 V DC.
