The Ubiquiti UniFi Access Retrofit PSU 12V (Model: UACC-Retrofit-PSU-12V) is a high-efficiency power supply unit engineered specifically for door access control systems requiring continuous power reliability. Designed as a dedicated companion power module for the UniFi Access Retrofit Hub, it enables smooth transitions when modernizing legacy door systems into the UniFi Access ecosystem without sacrificing power backup resilience.
Featuring support for an optional external 12V SLA (Sealed Lead-Acid) backup battery with a dedicated 0.5A charging circuit, the UACC-Retrofit-PSU-12V guarantees continuous system uptime and life-safety compliance during primary electrical disruptions. Its compact chassis houses an optimized internal power conversion circuit delivering up to 85% efficiency, alongside status LEDs that provide instant physical diagnostics for AC input, DC output, and battery health status.
Comprehensive Key Features:
Dedicated Retrofit Power Solution: Engineered explicitly for seamless native integration with the UniFi Access Retrofit Hub.
12V SLA Battery Backup Support: Features built-in charging management (0.5A charging current) for external 12V SLA backup batteries to maintain door operational integrity during grid failures.
High Output Rating: Delivers a continuous 12V DC output at up to 5A (80W maximum power consumption) to power connected access hardware cleanly.
85% Energy Efficiency: High-efficiency power conversion reduces thermal output and optimizes long-term operational costs.
Integrated Diagnostics: Equipped with 3 status LEDs for instant visual confirmation of input, output, and battery connection states.
Universal AC Input: Supports standard global grid inputs from 100V AC to 240V AC (50/60 Hz).
