-48 V DC redundant power supply

The HP 437573-B21 is a 1200 W Common Slot unit that accepts a -48 V DC input. It is built for hot-swap, tool-less installation into compatible server and storage platforms. The redundant design supports continuous operation in high-availability environments.

Suits HP BladeSystem c3000 enclosures.

This supply fits the HP BladeSystem c3000 enclosure and other hardware that uses the Common Slot form factor with a -48 V DC source. It will not operate in racks or servers that only provide AC mains power or that require a different mechanical interface.

1200 W maximum power rating

The single decisive specification is the 1200 W maximum output. If the connected chassis and installed modules draw more than this limit, the supply cannot deliver the required power and a higher-capacity Common Slot unit must be chosen.
