DC/DC converter for railway applications RWR 252-P400 series

isolatedregulatedencapsulated

This fully encapsulated, dual output, railway quality DC-DC converter uses a field-proven coupled inductor technology to generate the required output power. It is a mature product with a track-record in numerous applications. The total power is determined by the primary side current limiting and this power is shared by the outputs. This unit meets the requirements of EN50155 for electronic equipment used on rolling stock. It has an input voltage range to withstand RIA12 surges (3.5Vn for 20msec). The unit is entirely potted with a thermally conductive MIL-grade silicon rubber compound to ensure immunity to high levels of shock, vibration and humidity. Cooling is by conduction 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 is also suitable for transportation, mining, oilrigs, military and other harsh environments. It is manufactured at our plant under strict quality control. Customized versions are also available.
