Bel Fuse has expanded its RCM converter series with the RCM300 dual output DCDC converter for railway and transportation systems. The converters deliver 300W at +24/- 24V, while the two input voltage ranges cover all common railway batteries. The company states the two outputs are independently regulated, allowing tight and constant regulation even at extreme cross loads.
The converters are designed for chassis mounting and exhibit a closed housing. Applications include railway traction and auxiliary converters, plus railway power over ethernet (PoE) environments.
The converters have a five-year warranty and comply with EN50155, EN50121-3-2 and AREMA electrical standards; EN45545 and NFPA130 fire and smoke standards; and IEC/EN 62368-1 and UL/CSA 62368-1 safety standards.
Options include an output ORing FET for redundant operation, interruption time of 10ms (class S2), shutdown input and an output voltage monitor controlling a relay.
