Product Description
The HP 406405-001 is a 300-Watt power supply unit specifically designed to operate from a 48V DC input source. Unlike typical AC-powered PSUs found in standard desktop computers, this unit is intended for environments where DC power is the primary source, such as telecommunications closets, data centers with DC power distribution, or specific HP server and networking appliances. It converts the 48V DC input into the various DC voltage rails required by computer components, including +3.3V, +5V, +12V, -12V, and the standby +5VSB rail. The form factor of this power supply is likely specialized to fit within specific HP equipment chassis, rather than being a standard ATX form factor. This ensures a precise fit and proper integration within the intended hardware. Its primary function is to provide a stable and reliable power source for the sensitive electronics within servers, switches, or other network infrastructure devices that are designed to run on a nominal 48V DC power system. This is common in carrier-grade equipment and some enterprise data center deployments. Built for demanding operational environments, the 406405-001 includes essential protection mechanisms such as over-voltage protection, under-voltage protection, and short-circuit protection to safeguard the connected equipment. It also features an integrated cooling fan to manage thermal output during operation, ensuring longevity and consistent performance. This power supply is a critical component for maintaining the uptime and functionality of HP systems that rely on a 48V DC power infrastructure.
