Product Series
The RCM Series converters are Melcher branded power supplies for railway and transportation applications. The input voltage ranges cover all common battery voltages from 12 to 110 V. The output delivers 60 W at 12, 15 or 24 V. The converters are designed for chassis mounting in an enclosed housing. Options available include – output ORing FET for redundant operation, input fuse and output voltage monitoring (solid state relay contact).
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, 15 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 S2), shutdown input, and an output voltage monitor controlling a relay (change-over contact).
The RCM500 and RCM1000 Series converters are reliable power supplies for railway and transportation systems. They are optimized for 72 or 110 V railway batteries. The output delivers 24 V with 500 or 1000 W. 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, shutdown input, and a monitoring relay (change-over contact).
