Bel Power Unveils Railway-designed Melcher™ Cassette Converters

Bel Power Solutions has unveiled its Melcher™ LR Series 300 W AC-DC cassette converters, which are designed for railway and rugged industrial applications.

The LR Series products are an upgrade on Bel Power Solutions’ existing broad range of 19in cassette power supplies, ideal for situations requiring robustness and reliability.

Products feature a universal AC input voltage range, including active inrush current limitation and power factor correction. Two highly efficient and isolated outputs, from 12V to 15V up to 300W, offer maximised flexibility in system architecture and ensure they are uniquely suited to various railway applications, such as signalling, rugged communication, heavy-duty industrial control, and mission-critical defence and security systems.

The converters are incorporated in a rugged aluminium-extruded case and can operate in convection or conduction-cooled environments, at temperatures from -40° up to 85°C. All PCBs are conformally coated and protected against humidity and pollution which occurs during typical lifecycles of 20-plus years.

The LR Series is fully compliant and safety approved to the latest edition of IEC/EN 62368-1 and UL/CSA 62368-1. Underlining the high quality and reliability of the LR Series, Bel Power Solutions is offering an extended warranty of 5 years on all LR Series power converters.

The converters are fully protected against overload, over-voltage and over-temperature, under-voltage, no-load and short circuit with automatic recovery. Additional features include integrated holdup capacitors for 0.02 seconds interruption, an active current share for parallel and redundant operation, rectangular current limit characteristic and remote voltage adjust, inhibit and fail signal.

LR Series units are in stock with Digi-Key, Mouser and Arrow.
