Bel expands RCM Series for railway systems

The dual output converters are reliable power supplies, delivering 300W at +24 V/- 24 V, the two input voltage ranges covering all common railway batteries. 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. With low inrush current and extremely high efficiency and high power density, the devices are suitable for railway traction and auxiliary converters, along with railway power over ethernet (PoE) applications.

The RCM300 Series converters come with a five-year warranty and are compliant to EN 50155, EN 50121-3-2, and AREMA electrical standards, EN 45545 and NFPA 130 fire and smoke standards, and IEC/EN 62368-1 and UL/CSA 62368-1 safety standards.

Multiple feature options are available, such as an output ORing FET for redundant operation, interruption time of 10ms (class S2), shutdown input, and an output voltage monitor controlling a relay.

The new RCM300 Series dual output DC-DC converter is available immediately. Please contact Bel for stocking package pricing or modified and custom designs.
