Siemens 6EP3436-8SB00-0AY0 SITOP PSU8200 24V/20A 3AC Power Supply 400-500V

The Siemens 6EP3436-8SB00-0AY0 is a SITOP PSU8200 power supply that converts a 400-500V three-phase AC input into a regulated 24V DC output rated at 20A (480W), holding output within ±3% overall tolerance at 94% typical efficiency. It provides 15ms buffering on input loss, adjustable output from 24 to 28V, and DIN-rail mounting with screw terminals.

Selection Notes

The 480W/20A rating with 150% overload capability for up to 5s per minute lets this unit ride through motor-starting inrush on downstream DC loads without a separate buffer module for short transients — for longer ride-through, pair it with the listed buffer-module accessory rather than oversizing the PSU. Its 3-phase 400-500V input avoids the single-phase derating that a 1-phase SITOP unit would need at this power level, so it fits cabinets already wired for 3-phase distribution. The 15ms minimum buffering time at rated output covers brief mains dips typical of motor-heavy plants; confirm any load step beyond the specified 50/100/50% pattern before assuming the 0.2ms settling time holds.

Applications

Powers 24V DC control and I/O loads in cabinets fed from 400-500V 3-phase distribution — machine control panels, motor control centers, and process skids needing a single, higher-current 24V rail instead of several smaller supplies.
