The SITOP PSU3400 6EP3234-0TA00-0AY0 is Siemens' high-power 48VDC-to-24VDC DIN rail converter, delivering 256W at 10A for large 24V automation loads powered from 48V battery systems in marine and off-grid installations.

Core Function

Accepting 28-60VDC input (nominal 48VDC), this galvanically isolated converter provides a stabilized 24VDC output adjustable up to 28VDC. It enables full-scale 24V automation panels to operate from 48V battery banks, eliminating the need for separate AC distribution in DC-centric installations such as marine vessels, telecom shelters, and solar-powered sites.

Technical Specifications

At 93.5% efficiency, the 42mm-wide unit minimizes heat dissipation in sealed enclosures. A 120% continuous overload capability up to 45C ambient supports system expansions. Electronic protection covers short-circuit, overload, and reverse polarity. ABS and DNV certifications qualify for shipboard automation.

Installation

Snap-on 35mm DIN rail mounting. Screw terminals with dual output connections. A signaling relay provides remote status monitoring. Up to two units operate in parallel.
