Melcher RCM 150/300 DC-DC converters
Bel Power Solutions RCM Series converters comprise durable power supplies for railway and transportation applications.

There are two input voltage ranges covering all common railway batteries. The output delivers 150 W or 300 W at 12 V or 24 V. The converters are designed for chassis mounting and exhibit a closed housing.

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 (changeover contact).
