Siemens 6EP3434-3SB00-0AX0 SITOP PSU4200 3AC 24 V/10 A Power Supply

The Siemens SITOP PSU4200 6EP3434-3SB00-0AX0 converts a 3-phase 400/500 V AC input into a stabilized 24 V DC output rated at 10 A (240 W), with 90% typical efficiency and push-in terminals for both the 3-phase supply and output. It carries CE, UKCA, EAC, and RCM marking along with a UL 508 listing for global panel builds.

Selection Notes

The 3-phase 400/500 V AC input is what sets this variant apart within the PSU4200 family — choose it over a single-phase SITOP unit when the cabinet already runs a 3-phase supply, since spreading the load across three phases lowers the per-phase input current compared with drawing an equivalent 10 A output from a single phase. Its 5 ms minimum buffering time is short relative to single-phase SITOP units, so pair it with a downstream buffer module or DC UPS, both listed as compatible accessories, wherever the load cannot tolerate brief line dips. The 24-28 V adjustable output range gives headroom for cable-drop compensation on longer 24 V field runs.

Applications

24 V DC control-cabinet power fed from a 3-phase supply, machine builds running 400/500 V 3-phase mains, and panels needing push-in wiring at higher output current.
