- Description
The Siemens 6EP3233-0TA00-0AY0 SITOP PSU3400 is a DC/DC converter that steps a 48 V DC (28-60 V range) input down to a stabilized 24 V DC output at 5 A, adjustable up to 6 A. It reaches 92% efficiency and fits a 32 mm DIN-rail footprint for battery- or 48 V-bus-fed control cabinets.

Selection Notes
The 48 V DC input (28-60 V range) is what separates this PSU3400 unit from the AC-mains SITOP power supplies — choose it where the cabinet already runs a 48 V DC bus, such as a telecom-style battery system, rather than adding an AC feed. The output is adjustable 24-28 V via potentiometer, useful for compensating voltage drop on long 24 V DC runs instead of a fixed-output sibling. Two units can be connected in parallel to raise available current beyond the single-unit 5 A/6 A rating without moving to a higher-power PSU model.
Applications
48 V DC bus-fed control panels, telecom or battery-backed cabinets, and machine control needing a regulated 24 V feed from an intermediate 48 V rail.
