Description

The RCM Series converters are reliable power supplies for

railway and transportation systems. There are 2 input voltage

ranges covering all common railway batteries. The output

delivers 150 or 300 W at 12 or 24 V. The converters are

designed for chassis mounting and exhibit a closed housing

with cooling openings.

Many options are available, such as an output ORing FET for

redundant operation, output voltage adjustment, interruption

time of 10 ms (class ST2), shutdown input, and an output

voltage monitor controlling a relay (change-over contact).
