Ubiquiti UACC-PSU-UDW | Dream Wall Power Supply Unit

A 550W auxiliary power module that adds power redundancy to an existing UniFi Dream Wall installation.

Why this one

• The Dream Wall has no built-in redundancy path, so if the internal supply fails your entire network stack goes with it — this module provides the second feed that prevents that.
• At 550W output (54.8V DC, 10A), it matches the Dream Wall's power architecture directly, with no step-up or step-down conversion required at the unit.
• The 100–240V AC input range means it works on Australian mains without an adapter or external transformer.

Good fit if you have a UDW already running and uptime matters enough that a single PSU failure isn't an acceptable outage — typical in small server rooms, edge deployments, or anywhere the Dream Wall is carrying live PoE devices and active traffic.

Worth considering something else if you don't already own a Dream Wall, as this module has no function outside of that specific platform and isn't interchangeable with power supplies for other UniFi hardware.

What you'll also need

A UniFi Dream Wall (UDW) — this module only installs into that unit — and access to a standard Australian mains outlet at the mounting location.
