3U distributed power front-end

Emerson Network Power produces two 3U high modular ac-dc front-end power supplies for systems that use distributed power architectures (DPA) and intermediate bus architectures (IBA). Both power supplies are suitable for hot-swap and N+1 redundant applications.

The HPS15 has an output power rating of 1,500 watts. It has a 180 to 264 Vac input range, and is available with a main output voltage of 24, 28, 30, 48, 54 or 60 Vdc. As standard, the power supply also produces a 5 Vdc @ 5 A standby output; this is optionally available as a 3.3 Vdc @ 3 A output. A 12 V @ 4 A or 24 V @ 2 A fan output is also available as an option.

The HPS3KW has an output rating of 3,000 watts. It has a 180 to 264 Vac input range, with active power factor correction, and produces a main output of 51.4 Vdc @ 57 A. The power supply also produces a 5 Vdc @ 5 A standby output.
