The SITOP PSU3400 6EP3124-0TA00-0AY0 is Siemens' high-power 24VDC-to-12VDC DIN rail converter, delivering 200W at 15A for demanding 12V loads in industrial and marine applications.

Core Function

Accepting 14-32VDC input, this galvanically isolated converter provides a stabilized 12VDC output adjustable up to 15.5VDC at 15A. It powers high-current 12V equipment such as LED lighting arrays, thermal printers, vision system illuminators, and specialty motor controllers from the 24V control bus.

Technical Specifications

At 91% efficiency, the unit dissipates minimal heat for natural convection cooling. Electronic short-circuit protection with automatic restart and reverse polarity input protection ensure robust operation. ABS and DNV marine certifications qualify it for shipboard deployment.

Installation

The 42mm-wide housing mounts on 35mm DIN rails. Screw terminals for input (0.5-2.5mm) and dual output connections. A signaling relay provides remote status monitoring. Up to two units operate in parallel.
