HP PS-5551-2 500 Watts 220-240V Redundant Power Supply

Product Description

The HP PS-5551-2 is a high-performance, 500-watt power supply unit specifically engineered for redundant configurations in HP servers and storage systems. Operating within a 220-240V input range, this PSU is ideal for environments where stable, high-quality power is paramount. The redundant design means that two of these units can be installed in a compatible chassis, providing a failover mechanism. If one power supply unit fails, the other automatically takes over the entire power load, preventing system downtime and data loss. This power supply is designed for hot-swappability, allowing administrators to replace a faulty unit or upgrade without powering down the system. This feature is critical for maintaining high availability and ensuring that business-critical applications remain operational without interruption. The 500-watt capacity per unit is sufficient to power a wide range of server components, including multiple processors, extensive memory configurations, and numerous storage devices. Built to HP's rigorous standards, the PS-5551-2 ensures reliability, efficiency, and safety. It incorporates various protection circuits, such as over-voltage, over-current, and short-circuit protection, to safeguard the system from electrical disturbances. This makes it a robust and dependable choice for mission-critical deployments where uninterrupted operation is a key requirement.
