Dual output DC/DC converter covers all common railway battery voltages
The RCM series of DC/DC converters for railway systems by Bel Fuse has been expanded with the RCM300 dual output DC/DC converter for railway and transportation systems.
The dual output converter delivers 300W at +24V / – 24V. The two input voltage ranges cover all common railway batteries, said Bel. 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 high efficiency and high power density, the devices are suitable for railway traction and auxiliary converters, as well as railway power over Ethernet (PoE) applications.
The RCM300 Series converters are supplied 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.
There are optional features available, for example an output ORing FET for redundant operation, interruption time of 10ms (class S2), shutdown input and an output voltage monitor controlling a relay.
The RCM300 series dual output DC/DC converter is available immediately from distribution partners Digikey and Mouser.
Bel Fuse designs, manufactures and markets a broad array of products that include circuit protection, connectors, cable assemblies, discrete components, magnetics and power supplies for a variety of markets and operates facilities around the world.
