Ubiquiti UniFi · NDAA COMPLIANT
Mission-Critical Redundancy for UniFi Dream Wall
The Ubiquiti UACC-PSU-UDW is a high-efficiency 250W AC-to-DC hot-swappable power supply module purpose-built for the UniFi Dream Wall (UDW) ecosystem. Engineered to eliminate single points of failure in commercial security and enterprise network deployments, this secondary power unit delivers instant failover protection. By operating in tandem with the Dream Wall’s primary power module, it guarantees uninterrupted operation for high-density PoE applications, integrated security gateways, and cloud video management platforms.

Seamless Integration & Zero-Downtime Maintenance
Designed specifically to slide into the dedicated modular bay of your existing infrastructure, the Ubiquiti UACC-PSU-UDW provides enterprise-grade thermal management and automatic load balancing. In the event of an AC supply failure or primary PSU issue, the secondary module seamlessly takes over the full load without causing hardware resets or packet loss across downstream switches, UniFi Protect cameras, and access control endpoints. Its toolless, hot-swappable design ensures IT administrators can perform maintenance or upgrades with absolute zero network downtime.
1+1 Hot-Swappable Redundancy
Protects your wall-mounted enterprise rack deployment against power outages. If the primary power supply drops, the UACC-PSU-UDW instantaneously handles the operational power load to keep security feeds and network infrastructure live.
Maximized PoE Budget Support
Supplies up to 250W of clean, continuous AC power, helping maintain maximum PoE+ and PoE++ output capability across all connected access points, IP cameras, and smart building sensors.
