Encapsulated DC/DC converter for Railway and other Heavy-duty Applications delivers 50W

The RWY 50-72/48 is a recent addition to Absopulse Electronics’ RWY Series of rugged, field-proven, DC/DC converters. Designed for operation in railway and other harsh environments, this 50W, single output converter delivers 48Vdc, and accepts an input voltage of 72Vdc (42V to 110Vdc range). Although a unique input/output configuration, the design is based on the same field-proven topology as the company’s extensive range of encapsulated DC/DC converters.

This converter meets the stringent requirements of EN 50155 for electronic equipment used on railway rolling stock. It also meets EN 50121-3-2 (EMI and EMC) and EN55022 Class B EMI, with wide margins. Full encapsulation in a thermally conductive MIL-spec. silicon rubber compound ensures immunity to shock, vibration, moisture, salt and airborne contaminants. The RWY 50-72/48 is designed to meet IEC 61373 Categories 1 A & B and Category 2 shock and vibration standards. Conduction cooled via a base plate, the unit performs to full specification at temperatures from -40°C to 70°C, cold plate. The compact P100 chassis measures 2.3". x7.1” x 2.4”.
