HP 30-56549-01 ProLiant Power Supply

The HP 30-56549-01 is a Delta Electronics DPS-1085AB A power supply unit, originally fitted to Compaq (now HP, following the 2002 merger) server platforms. It’s a hot-swappable switching power supply module rated for server-class loads, built by Delta Electronics, one of the principal OEM power supply manufacturers used across Compaq and HP’s server ranges. As a redundant PSU module, it slots into the server’s power bay to provide DC output to the system board, drives and other internal components, with a second unit typically fitted alongside it for N+1 redundancy so the server keeps running if one supply fails. It’s a straightforward like-for-like replacement part for engineers maintaining older Compaq/HP server deployments still in service. Tech-Star (UK-based, shipped worldwide) supplies tested server power supplies. Enquire to confirm fit with your exact server model before ordering.
