This fully encapsulated, dual output, railway quality DC/DC converter uses a field-proven high efficiency power conversion topology to generate 250W output power. The unit has two fully independent, regulated isolated output stages, V1 providing up to 140W and V2 up to 110W. The design is based on the field-proven RWY 150 and RWY 100 series topology, which has a track record in numerous applications. It is entirely potted with a thermally conductive MIL-grade silicon rubber compound to ensure immunity to shock, vibration and humidity. The unit is conduction cooled via a base plate to a heat-sinking surface. Low component count, large design headroom, and the use of components with established reliability result in a high MTBF. It meets the requirements of EN50155 for electronic equipment used on rolling stock. The unit is also suitable for transportation, mining, military, marine and other harsh environments. The series is manufactured at our plant under strict quality control. Customized versions are also available
