BEL POWER SOLUTIONS INC RCM500 DC-DC Converter, 24V dc/ 21A Output, 77 → 137.5 V dc Input, 500W, Chassis Mount,

Rugged Melcher™ Cassettes style converters, with their one to three fully-isolated and regulated outputs, are well-suited for applications from rail, communications and industrial where tough, reliable power is paramount.

The RCM500 and RCM1000 Series converters are reliable power supplies for railway and transportation systems. They are optimized for 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 slots. 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 a monitoring relay (change-over contact).
