150W and 300W DC-DC Converters for Railway Applications

March 28, 2018 by Paul Shepard

Bel Power Solutions and Protection has announced the RCM150 (150W) and RCM300 (300W) chassis-mount dc-dc converters, which are designed for railway applications where compactness and high reliability are required. These new RCM Series products are fully isolated and highly efficient over a broad operating range of input and output voltages.

In addition, their compact size and ease of installation make them suited for various rolling stock applications, such as cab radios, HVAC systems, train control, passenger information systems, toilet systems, illumination and many others.

RCM Series are fully compliant to international railway standards EN 50155, EN 50121-3-2, EN45545-2 and North American AREMA requirements.In addition, the RCM Series is safety approved to the latest edition of IEC/EN/UL 60950-1.

Nominal on board battery voltages from 24V to 110V are covered by two input ranges and converted into a fully regulated and isolated single output voltage of 12V or 24V.

The converters can operate in a convection cooled environment at temperatures from -40° up to 85°C. All PCBs are conformal coated and protected against humidity and pollution which occurs during typical lifecycles of +20 years of rolling stock equipment.

The converters are fully protected against over-load, -voltage, -temperature, under voltage, no-load and short circuit with automatic recovery. Additional features include integrated hold-up capacitors for 10ms interruption, ORing FET and passive current share for parallel and redundant operation, as well as remote voltage adjust, enable and fail signal.

RCM150 units are currently in stock with Digi-Key, and RCM300 units are expected to be available in April.
