Power Adapter for UniFi Retrofit Hub

This 12 V power adapter is built for the UniFi Retrofit Hub and supports an optional sealed lead-acid backup battery. It accepts 100240 V AC at 50/60 Hz and delivers up to 80 W of DC power. The unit measures 127 x 76 x 35 mm and weighs 350 g, making it a compact addition to a network cabinet. Installers who need continuous uptime during mains outages will appreciate the integrated battery charging circuit.

Wiring and Space Requirements

The adapter provides three connections: an AC input, a DC output for the Retrofit Hub, and a DC input/output for the backup battery. A charging current of .5 A maintains the 12 V SLA battery without extra hardware. Because the power supply handles both the hub and battery charging from a single AC feed, it reduces the number of wall outlets and cable runs needed in the rack. The 5 x 3 x 1.4 inch footprint fits on standard shelving or DIN rail trays.

Upgrade from Basic Wall-Wart Supplies

Replacing a simple plug-top transformer with this unit adds managed battery backup and a unified wiring point for the Retrofit Hub. The jump is worthwhile when the installation must survive short power interruptions without dropping network connectivity. Sites that do not require battery redundancy or that already run a separate UPS will not gain additional benefit from the integrated charging feature.

Questions about this item

How much power does the UACC-Retrofit-PSU-12V draw at maximum load?

The adapter is rated for a maximum power consumption of 80W when supplying the Retrofit Hub and charging the backup battery.

How warm or noisy does the 12V PSU get during continuous 24/7 operation?

The unit has no fan; it relies on passive cooling through its 127 x 76 x 35 mm metal enclosure, so it runs silently and stays warm but within normal limits for a sealed 80W supply.

Which UniFi device must I already own for this power supply to function?

It is designed exclusively for the UA-Retrofit-Hub-2 and will not power any other UniFi hardware.
