ABSOPULSE Electronics’ RWD 200-P200L and RWD 200-P200X fully encapsulated, DC-DC converters deliver up to 200W for redundant/parallel operation in rolling stock applications.
The converters operate from a 24Vdc, 36Vdc, 48Vdc, 72Vdc, 96Vdc, 110Vdc or custom input voltage, with wide EN50155 input ranges. The units deliver 12Vdc/16A, 24Vdc/8A or custom output voltage. Conversion efficiency is between 80 to 90%, depending on input/output configuration.
The railway DC-DC converters have a built-in redundancy diode for redundant and parallel operation of several units. The units have special circuitry to lower the hiccup threshold, which makes them suitable for paralleling. An output fail alarm would be triggered if one of the connected units fails.
The RWD 200-P200L and RWD 200-P200X converters meet the requirements of EN50155 for electronic equipment used on railway rolling stock. The units have heavy filtering on the input and output and comply with EN50121-3-2. The converters also meet EN61000-4-2 (ESD), EN61000-4-3 (RF Immunity), EN61000-4-4 (Fast Transients), and EN61000-4-6 (Conducted Immunity). Other protection features include 3000Vdc input-output isolation, reverse polarity protection, overload protection, thermal protection and current limiting.
The converters are fully encapsulated with a thermally conductive MIL-grade silicon rubber compound with a UL94V-0 flammability rating and meet environmental criteria as requested in MIL-810C, D. Conduction cooling via base plate to customer chassis or heat-sink enables operation over a -40°C to +70°C temperature range for full specification without derating.
