2400W modular AC supply for BladeSystem c7000

This hot-plug power module delivers up to 2400 W of AC power for HP BladeSystem c7000 enclosures. It operates on a 200 V to 240 V input range and draws 12.60 A at 220 V. The modular design allows tool-less insertion and removal while the enclosure remains powered.

Gold 92% efficiency under continuous load

Certified at 92 per cent efficiency, the unit reclaims power that would otherwise be lost as heat during sustained operation. This reduces overall enclosure power draw and thermal output when the chassis runs at high utilisation for extended periods.

Replaces lower-wattage or non-hot-plug modules

The 2400 W capacity supports fully populated blade configurations that smaller supplies cannot sustain. The jump is worth it when the enclosure demands maximum density and zero-downtime module swaps.

Questions about this item

How much heat does the 2400W unit produce when running continuously at full load?

At 92% efficiency the supply converts most input power, leaving roughly 200 W of waste heat that the enclosure fans must remove around the clock.

What infrastructure must already be in place for this supply to operate?

It requires an HP BladeSystem c7000 enclosure and a 200 V AC to 240 V AC three-phase source capable of delivering 12.60 A at 220 V AC.

Will the module work alongside older power supplies already installed in the same c7000 chassis?

Yes, the hot-plug modular design lets it share the enclosure's power bus with existing supplies without shutting down the blade servers.
