Bel Power Solutions Releases Connector for RCM DC-DC Converters for Railways

Bel Power Solutions and Protection has announced an extension to the RCM Series, 150W to 1,000W chassis-mount DC-DC converters, with an optional pluggable connector version.

The pluggable connectors are an alternative to the standard cage clamp terminals that lower the risk of reverse polarity connection and supports the integration of ready-made cable harnesses during installation, as well as for maintenance purposes.

The pluggable connectors are from established connector manufacturers in the railway industry and provide additional retention facility for shock and vibration-proof operation in various rolling stock applications such as cab radios, heating, ventilation and air-conditioning systems, train control, passenger information systems, toilet systems, lighting and many others.

RCM Series are fully compliant to international railway standards EN 50155, EN 50121-3-2, EN 45545-2 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° to 85°C. All PCBs are conformal coated and protected against humidity and pollution, which occurs during typical lifecycles of more than 20 years of rolling stock equipment.

The converters are fully protected against overload, overvoltage, overtemperature, 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. These innovations make the RCM Series DC-DC converters ideal for a broad range of applications in the global railway market.
