400W, Rugged, Encapsulated DC-DC Converter for Heavy Duty Applications PDC 400-P400 Series • • • • • • Rugged, field-proven design Fully encapsulation (potting) Conduction cooling Full electronic protection Wide temperature range Wide input ranges This fully encapsulated, rugged, industrial quality, DC-DC converter uses field-proven technology to generate the required output power. It is a mature product with a track-record in numerous applications. The converter is entirely potted with a thermally conductive MIL-grade silicon rubber compound to provide immunity to shock, vibration and humidity. Cooling is via baseplate by conduction. The unit is designed for continuous operation at 70°C with installation on an appropriate size of heat-sinking surface. Full electronic protection, low component count, large design headroom, and the use of components with established reliability ensure high MTBF. The unit is suitable for transportation, mining, oil rigs, military and other harsh environments. Versions that are designed to meet EN 50155 railway specifications are also available. Optional alarms and a redundancy diode are available on custom versions. The converter is manufactured at our plant under strict quality control.
