The SITOP PSU300S 6EP1436-2BA10 is Siemens' 480W 3-phase DIN rail power supply, engineered for demanding factory automation and marine applications where high current delivery and reliability are paramount.

Core Function

Converting 3-phase AC input (340-550V) to a stabilized 24VDC output adjustable up to 28VDC, this 20A supply powers large PLC systems, distributed I/O, and drive controllers. The 150% power boost delivers up to 30A momentarily to handle motor-start and capacitive inrush currents without voltage sag.

Technical Specifications

With 91% efficiency and natural convection cooling, the unit operates reliably across -25C to +60C without a fan. Comprehensive electronic protection covers short-circuit, overload, and overvoltage conditions with automatic recovery. A signaling relay integrates with plant monitoring systems for remote status indication.

Installation and Integration

Snap-on DIN rail mounting fits standard EN 60715 35mm rails. Compatible with SITOP buffer, DC-UPS, redundancy, and selectivity modules for building complete power management solutions.
