for Heavy-duty Industrial Applications PDC 250-HSA-P59 Series • Rugged, field-proven design • Fully encapsulated module installed on heatsink assembly • Convection cooling via heatsink assembly • Full electronic protection • Wide temperature range • Wide input ranges • DIN-rail mounting available This fully encapsulated, 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. Encapsulation ensures heat dissipation throughout the module. Convection cooling is achieved by installing the unit on a heatsink assembly block which is specifically designed for the unit. The heatsink assembly also allows for mounting on uneven and thermally non-conductive surfaces. 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, oilrigs, military and other harsh environments. The converter is manufactured at our plant under strict quality control. DIN-rail mounting is available on request. Versions that are designed to meet EN50155 railway specifications are also available.
