The SITOP PSU3400 6EP3233-0TA00-0AY0 is Siemens' 48VDC-to-24VDC DIN rail converter, delivering 130W at 5A to power 24V automation equipment from 48V battery banks in marine, off-grid, and telecom installations.

Core Function

Accepting a wide 28-60VDC input range (nominal 48VDC), this galvanically isolated converter provides a stabilized 24VDC output adjustable up to 28VDC. It enables standard 24V automation equipment to operate from 48V battery systems commonly found in marine vessels, telecom sites, and renewable energy installations.

Technical Specifications

Operating at 92% efficiency in a compact 32mm-wide housing with natural convection cooling. Electronic short-circuit protection with automatic restart, reverse polarity protection, and very low no-load losses. ABS and DNV marine certifications qualify it for shipboard use.

Installation

Snap-on 35mm DIN rail mounting. Screw terminals for 0.5-2.5mm wiring. A signaling relay contact enables remote monitoring. Up to two units operate in parallel.
