LR Series AC-DC Converters for Railway & Rugged Applications

The new 300 Watt LR Series from Melcher represents an extension to the existing broad range of 19” cassette Power Supplies and DC-DC Converters, and are ideal for applications working in rugged conditions and where high reliability is required.

The products feature a universal AC Input Voltage range including active inrush current limitation and power factor correction (PFC). Two highly efficient isolated outputs of 12 or 15 V up to 300 W offer maximum flexibility in system architecture and make them especially suitable for a number of railway applications such as signalling, rugged communication as well as heavy-duty industrial control, and mission-critical defence or security systems.

LR Series – Rugged Cases & 19″ Rack Options

The converters are incorporated in a rugged aluminium extruded case, with options for bespoke 19″ subracks, and can operate in a convection / conduction cooled environment at temperatures from -40° up to 85°C. All PCBs are conformal coated for protection against humidity and pollution which occurs during typical lifecycles of +20 years.

The LR Series are 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 over-load, -voltage, -temperature, under voltage, no-load and short circuit with automatic recovery.

Additional features include integrated hold- up capacitors for 20ms interruption, active current share for parallel and redundant operation, rectangular current limit characteristic and remote voltage adjust, inhibit and fail signal.
