Siemens 6EP3332-3SB00-0AX0 SITOP PSU4200 1AC 24V/3A Power Supply

The Siemens SITOP PSU4200 (6EP3332-3SB00-0AX0) is a single-phase stabilized power supply that converts a 120/240 V AC input into a regulated 24 V DC output rated 3 A / 72 W. It buffers the rated output current for a minimum of 15 ms on power loss and reaches 85% efficiency, with output adjustable from 24 to 28 V via potentiometer.

Selection Notes

The 3 A output covers compact 24 V DC loads such as a single SIMATIC S7-1200 station without stepping up to the same series' 6 A or 10 A units. Adjustable output up to 28 V compensates voltage drop on longer DC feeder runs, and the 15 ms buffering time rides through typical mains dips without an external UPS module.

Applications

Powers compact SIMATIC S7-1200 machine controllers, 24 V DC sensor/actuator circuits, and panel builds where enclosure width is limited, since the housing is only 50 mm wide.
