2U Distributed Power Front-End
Emerson Network Power produces three 2U high modular ac-dc front-end power supplies for systems that use distributed power architectures (DPA) and intermediate bus architectures (IBA). The power supplies feature wide-range ac inputs and active power factor correction, and produce a main 12 Vdc output and a 3.3 Vdc standby output. The power supplies are suitable for hot-swap and N+1 redundant applications, have active current sharing facilities, and are equipped with I2C communication interfaces. Output power ratings range from 600 watts up to 1,500 watts.
