Protect service continuity with a replacement power module designed for Ubiquiti enterprise systems that cannot afford extended downtime. This 550 W AC-to-DC supply is built for hot-swap replacement in CloudKey Enterprise, Enterprise Aggregation, and Enterprise NVR platforms, allowing maintenance teams to restore power without shutting down the host. For infrastructure teams, the value is operational: fewer service interruptions, faster recovery from PSU failure, and a cleaner spare-parts strategy across supported Ubiquiti deployments. The compact module form factor fits the intended hardware footprint, while the included power cable reduces the friction of field installation. This is the right choice when you need the exact replacement part for supported Ubiquiti appliances rather than a generic alternative. It preserves compatibility, keeps power delivery aligned to the platform design, and helps protect the higher cost of downtime in edge and core management environments.
