The RWY 182 Series fully encapsulated, dual output, railway quality DC/DC converter uses field?proven topology to generate 200W output power. It employs forward topology on one output and push pull topology on the other.ÿÿBoth outputs are individually regulated and current limited.This is a mature product with a track?record in numerous applications.The unit is entirely potted with a thermally conductive MIL?grade silicon rubber compound to ensure immunity to shock, vibration and humidity.ÿÿIt 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. The unit meets the requirements of EN50155 for Electronic equipment used on rolling stock. The unit is also suitable for transportation, mining, oilrigs, military and other harsh environments.ÿ
