Bel Power Solutions Announces Connector for Melcher RCM Chassis-Mount DC-DC Converters

04 October 2018

Bel Power Solutions and Protection, a Bel group company and global manufacturer of power management devices, announces an extension to the RCM series, 150 W to 1000 W, chassis-mount DC-DC converters, with an optional pluggable connector version.

The pluggable connectors are an alternative to the standard cage clamp terminals, which lowers 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 Source: Bel Power SolutionsSource: Bel Power Solutionswell-accepted 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, HVAC systems, train control, passenger information systems, toilet systems, illumination and many others.

RCM series devices 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 onboard battery voltages from 24 V to 110 V are covered by two input ranges and converted into a fully regulated and isolated single-output voltage of 12 V or 24 V. 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 the typical lifecycle of 20-plus years for 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 10 ms interruption, O-ring 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.
