1200Vdc Input, Rugged, 5kW DC-DC Converter for Heavy-duty Industrial Applications HVT 5K-1200/24-4U7 Series • • • • • 1200Vdc nominal input (1000V-1400V) Field-proven design topology For rugged industrial applications Cooling by high quality built-in fans Full electronic protection This rugged, industrial quality DC-DC power converter utilizes field proven technology to generate the required output power. The design is based on mature design topology with a track record in numerous applications. The unit is built with two FHD 3010 and four JHI 1500 internal modules. The input and output are filtered for low noise. High quality built-in fans provide sufficient airflow for operation within the specified temperature range without de-rating. The fans draw air into the unit which exhausts at the fan side of the unit. All heat generating components are installed on aluminum heatsink blocks which are thermally connected to the base plate. This also ensures exceptional mechanical ruggedness. Conformal coating provides protection against humidity and airborne contaminants. Full electronic protection, low component count, large design headroom, and the exclusive use of components with established reliability contribute to a high MTBF. The unit is manufactured at our plant under strict quality control.
