HP 449838-001 750W Hot-Pluggable AC Power Supply

HP 449838-001 – Redundant Power Supply

Overview :

The HP 449838-001 is a 750‑watt hot‑swappable redundant power supply module designed for enterprise servers such as the ProLiant DL180 G5 and DL185 G5. It enables IT engineers to maintain continuous power delivery and replace PSU units without downtime, supporting dual‑module redundancy in two‑PSU server environments. The unit accepts an AC input range of 100–240 V at 50/60 Hz and provides a single +12 V rail rated at up to 62.5 A, making it suitable for high‑density server configurations. It fits within data centre or rack‑mounted server deployments and integrates with HP’s built‑in power management and system health monitoring tools. Because it is hot‑pluggable and designed for redundant operation, it supports field servicing and swap‑out without shutting down the server chassis.
