2U distributed power front-end

Emerson Network Power produces two 2U high modular ac-dc front-end power supplies for systems that use distributed power architectures (DPA) and intermediate bus architectures (IBA). Both 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.

The DS1300 has an output power rating of 1,300 watts, while the DS1500 has an output power rating of 1,500 watts.
