250W, Rugged Dual output DC/DC Converter for Railway and other Heavy Duty Applications
The RWY 250 series dual-output converter provides a maximum output of 250W. It employs forward topology on one output and push- pull topology on the other. Both outputs are individually regulated and current limited. This high-density unit is entirely potted with a thermally conductive MIL-spec. silicon rubber compound for resistance against shock, vibration, humidity, moisture, dust and insects. The converter is conduction cooled via a base plate and designed for operation within a wide temperature range without de-rating. The use of components with many years of established reliability and generous headroom contribute to a the demonstrated MTBF exceeding 1,000,000 hours at typical operating temperatures. The unit is intended for transportation, mining, oil rigs, military and other harsh environments. This design meets the requirements of EN50155 for electronic equipment used on rolling stock.
