The SITOP PSU3400 6EP3123-0TA00-0AY0 is Siemens' compact 24VDC-to-12VDC DIN rail converter, delivering 107W at 8A for powering 12V equipment from a standard 24V industrial control bus.

Core Function

Accepting 14-32VDC input, this galvanically isolated converter provides a stabilized 12VDC output adjustable up to 15.5VDC. It supplies clean power to 12V sensors, vision systems, lighting, and specialty controllers without requiring a separate AC/DC supply. Electronic short-circuit protection with automatic restart ensures continuous operation.

Technical Specifications

Operating at 90% efficiency, the 32mm-wide unit requires only natural convection cooling. Marine approvals (ABS, DNV) qualify it for shipboard use. A green LED indicates output status. Reverse polarity protection at the input prevents installation damage.

Installation

Snap-on 35mm DIN rail mounting. Screw terminals accept 0.5-2.5mm wiring. Up to two units operate in parallel. Fifty millimeters of top/bottom clearance is required for cooling.
