The SITOP PSU3400 6EP3133-0TA00-0AY0 is Siemens' high-efficiency 24VDC-to-24VDC DIN rail stabilizer, delivering 130W at 5A to protect sensitive loads from input voltage fluctuations in battery-buffered and long-cable-run applications.

Core Function

Accepting 14-32VDC input, this galvanically isolated converter provides a tightly regulated 24VDC output adjustable up to 28VDC. It ensures clean power to PLCs, HMIs, and communication equipment even when the source voltage sags due to battery discharge or cable voltage drop. The 93% efficiency minimizes heat in sealed enclosures.

Technical Specifications

Electronic short-circuit protection with automatic restart and reverse polarity input protection ensure reliable operation. Marine certifications (ABS, DNV) enable shipboard deployment. A green LED indicates output status.

Installation

The 32mm-wide housing mounts on 35mm DIN rails with no lateral spacing required. Screw terminals accept 0.5-2.5mm wiring. Up to two units operate in parallel.
