This fully encapsulated, railway quality DC/DC converter uses field-proven technology to generate the required output power. The design is based on field-proven topology, which has a track record in numerous applications. The use of the latest semiconductor technology enables lower component count than earlier generations. Comprehensive electronic protection, generous design headroom and the use of components with established reliability ensure high MTBF. The unit is entirely potted with a thermally conductive MIL-grade silicon rubber compound which provides immunity to shock, vibration and humidity. An optional built-in redundancy diode allows for parallel and N+1 operation. Cooling is by conduction via a base plate to a heat-sinking surface.
