RCM (Railway Chassis Mount) DC-DC converters

RCM Series (Railway Chassis Mount) DC-DC converters are reliable power supplies for railway and transportation systems. There are two wide input voltage ranges available for 150 W and 300 W models, while 500 W and 1000 W models are optimised for 110 V railway batteries. The RCM Series is designed for chassis mount applications operating in convection cooled environments. Many options are available, such as an output ORing FET for redundant operation, output voltage adjustment, interruption time of 10 ms (class S2), out-ok signals, and a shutdown input.
