Alpha Cordex HP 48V DC Power System

Alpha Cordex HP 48V DC Power System

The Cordex HP 1.2kW is a perfect solution for small 48Vdc power applications such as customer premise, xDSL, FTTx, distributed node B, and microwave. With a high operating efficiency and high temperature operation, HP series rectifiers are also ideal for harsh outside plant enclosure installations.
