Introduction

The 3U 12HP power supply unit is a plug-in device for 19" systems (e.g. VMEbus, CompactPCI®) and is especially designed for railway computer systems, being fully compliant with EN 50155.

The 1.5 kV (effective) optically isolated PSU comes with a nominal input of 110 V DC (66-154 V) and a single output of 5 V at 80 W. It works up to +85°C without derating, delivering a thermal warning at overtemperature and switching off at +95°C.

The PSU supports an error signal (5 ms hold-up time), reverse-connect protection, permanent short-circuit protection, voltage control, synchronization, voltage in fail (ViF) and voltage out fail (VoF) as well as remote on/off.

The subassembly is immersion-painted und partially cast, and components are secured against vibration. The thermal stress is extremely low due to integrated heat sinks and diversion of dissipated heat over the mounting surface.
