Ubiquiti Retrofit PSU 12V - UACC-Retrofit-PSU-12V
Ubiquiti UACC-Retrofit-PSU-12V Retrofit PSU 12V AC/DC power supply for UniFi Access Retrofit Hub 2, 12V DC @ 5A output, supports 12V SLA backup battery with built-in charger, compact design with LED status indicators
Ubiquiti Retrofit PSU 12V (UACC-Retrofit-PSU-12V)
Retrofit PSU 12V is a dedicated AC/DC power supply with a 12 V output voltage, designed to work with the UniFi Access Retrofit Hub 2 (UA-Retrofit-Hub-2) door controller. The device provides stable 12 V DC power with a maximum load of 5 A for access control system components, while also supporting connection of an optional 12 V SLA backup battery to maintain system operation during mains power outages.
The Retrofit PSU 12V is equipped with dedicated connection terminals: a separate AC mains input, a DC output port for powering the Retrofit Hub, and an additional battery terminal for the SLA battery. The built-in charging circuit supplies a regulated charging current (0.5 A), keeping the connected battery in a fully charged state. The device features compact dimensions (127 × 76 × 35 mm) and includes three status LEDs for monitoring system power conditions.
Key Features
- Dedicated 12 V DC power supply for the UniFi Access Retrofit Hub 2 (UA-Retrofit-Hub-2).

UACC-Retrofit-PSU-12V – Frequently Asked Questions (FAQ)
Does the Retrofit PSU 12V work without a backup battery?
Yes. The Retrofit PSU 12V can operate without a backup battery, but only as a DC power supply—backup and battery charging features will be disabled.
How does the SLA battery interface work?
When AC power is available, the Retrofit PSU 12V powers the device and charges the SLA battery. If AC power is lost, the SLA battery automatically supplies the DC output, maintaining system operation.
What type of SLA battery is supported?
The Retrofit PSU 12V supports 12 V sealed lead-acid (SLA) batteries.
Does the Retrofit PSU 12V protect the battery from overcharging?
Yes. The charging circuit in the Retrofit PSU 12V includes overcharge protection, enhancing battery safety and prolonging service life.
