500W IP66-Rated Rugged Industrial Quality DC-DC Converters BAP 319-D4 Series (IP66) • • • • • • Packaged in waterproof IP66 enclosure Internal module ruggedized and conformal coated Regulated output Full electronic protection Rugged field-proven design N+1 redundancy available The rugged industrial quality DC-DC converters use field proven topology to generate the required output power. The units are enclosed in robust, waterproof, die cast aluminum D4 size IP66 packages. The input and output are via sealed cable glands, circular connectors or custom connections. The internal boards are ruggedized and conformal coated for immunity to high levels of shock and vibration. Cooling is by internal conduction to the walls of the IP66 enclosure and by baseplate to an external chassis or cabinet wall, with additional convection via the outside surface. If installed on a heat-sinking surface, cooling is further enhanced and the converters achieve higher output power. An optional built-in redundancy diode allows for parallel and N+1 operation. Full electronic protection, low component count, large design headroom, and the use of components with established reliability contribute to high MTBF. The unit is manufactured at our plant under strict quality control.
