Chassis-Mount 500W and 1000W DC-DCs for Railway Applications
Bel Power Solutions and Protection announced the RCM500 (500W) and RCM1000 (1000W) 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 uniquely 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 72V to 110 are covered by two input ranges and converted into a fully-regulated and isolated single output voltage 24V.
The converters can operate in convection and conduction cooled environments 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 active current share for parallel and redundant operation,
- and remote voltage adjust, enable and fail signal.
RCM500 and RCM1000 units are currently in stock with Mouser, Digi-Key and Arrow, as well as other online distributors.
