Ubiquiti UACC-RETROFIT-PSU-12V | Retrofit Power Supply 12V

A 12V DC power supply designed to drive the UniFi Retrofit Hub, with a wiring terminal for an optional SLA backup battery so the hub stays up if mains power drops.

Why this one

• The dedicated SLA battery terminal (12V, 0.5A charging current) means you can add a backup battery without a separate UPS — useful for access control installs where a power cut shouldn't mean an open door.
• Universal 100–240V AC input means it runs on Australian mains without an adapter or separate power conversion.
• At 12V DC, 5A output and 80W max consumption, it provides enough headroom for the Retrofit Hub and connected devices without needing an oversized supply.
• Three status LEDs let you confirm mains power, battery state, and output at a glance without opening the UniFi app.

Good fit if you're deploying a UniFi Retrofit Hub and want onsite battery backup built into the same unit rather than relying solely on mains power.

Worth considering something else if your install doesn't include a Retrofit Hub — this supply is designed specifically for that device and isn't a general-purpose 12V source for other UniFi hardware.

What you'll also need

A UniFi Retrofit Hub (sold separately) and, if you want battery backup, a 12V SLA battery — the supply includes the charging circuit but the battery itself is not in the box.
