The FHW500R is an ultra high efficiency 500 W DC/DC converter for use in powering wireless base stations and other high current 24 - 28 V DC applications. The FHW500R operates over an input voltage range of 36 V DC - 75 V DC (48V nominal) to deliver a single output of 24 - 28 V DC in an industry standard full brick package. Advanced synchronous rectification technology enables the FHW500R to achieve efficiency levels of up to 91% at 28 V, 18 A full load. The FHW500R is designed to operate in temperatures ranging from 㫀°C to 100°C. A metal board construction allows cold wall assembly and the possible addition of heat-sinks, ensuring high performance over the extended temperature ranges typically seen in wireless base stations.
