The SITOP PSU3400 6EP3332-0TA00-0AY0 is Siemens' universal-input DIN rail power supply, accepting any voltage from 88-264VAC or 18-264VDC to deliver 85W at 2.5A of stabilized 24VDC.

Core Function

This uniquely flexible supply accepts both AC line voltage and DC battery voltage on the same input terminals, eliminating the need for separate AC and DC supplies in mixed-source applications. It powers small PLCs, RTUs, and communication equipment in installations that may transition between grid and battery power.

Technical Specifications

Operating at 85% efficiency with very low no-load losses (1.5W max), the 32mm-wide unit features electronic short-circuit protection with automatic restart, reverse polarity protection, and galvanic isolation. ABS and DNV marine certifications extend deployment to shipboard systems.

Installation

Snap-on 35mm DIN rail mounting in a compact 32mm-wide housing. Screw terminals accept 0.5-2.5mm wiring. Compatible with SITOP accessory modules for buffered and redundant configurations.
