The SITOP PSU300E 6EP1433-0AA00 is Siemens' ultra-compact 3-phase DIN rail power supply, delivering 120W at 5A in a 42mm-wide housing for space-constrained control panels.

Core Function

Accepting a wide 3-phase AC input (320-550V), this stabilized supply provides a clean 24VDC output adjustable up to 29VDC. Designed for small PLCs, HMIs, sensors, and actuators, it delivers reliable power without the complexity of single-phase load balancing.

Technical Specifications

Operating at 90% efficiency with natural convection cooling, the PSU300E requires no fan and mounts side-by-side without clearance gaps. Electronic short-circuit protection with automatic restart ensures continuous operation. A front-panel green LED and relay contact signal output status for plant monitoring.

Installation and Integration

At just 42mm wide, this power supply maximizes panel space. Removable screw terminals speed wiring and replacement. It integrates with the SITOP ecosystem for future upgrades to buffered or redundant configurations.
