- Description
Siemens 6EP3336-3SB00-0AX0 is a SITOP PSU4200 stabilized power supply delivering 24 V DC at 20 A from a 120-240 V AC, 50/60 Hz input. It reaches 93% typical efficiency, provides a floating DC-OK signal contact, and includes push-in terminals rated for up to 6 mm2 on the output side in a 70 x 135 x 125 mm DIN-rail housing.

Selection Notes
At 20 A / 480 W typical output, the PSU4200 sits mid-range in the SITOP power supply family - loads under about 4-5 A are better served by a smaller supply with a lower footprint, while continuous loads above 20 A require the next current step up in the same series. The floating DC-OK signal contact lets a PLC monitor supply health directly, a feature not present on LED-only indicated supplies. Push-in terminals rated to 6 mm2 on the output support the higher current without derating the connection.
Applications
Sized for machine control cabinets, motor starter panels, and PLC/IO racks needing a single 20 A, 24 V DC bus with supply-health signaling back to the controller.
