Specialized power supply module for UniFi Access system installation.
The UniFi Access Retrofit PSU 12V power supply module is a key component for integrating modern UniFi access system readers into existing installations. The module provides efficient voltage conversion from 100–240 V AC to stable 12 V DC with a maximum output of 80 W and efficiency of 85%.
The device supports connection of a 12 V SLA backup battery with a charging current of 0.5 A, ensuring uninterrupted operation of the access system even during power outages. Compact dimensions of 127 × 76 × 35 mm and weight of 350 g allow for easy installation in space-constrained locations.
Connectivity and wiring
The module features three connectors: AC input for mains power connection, DC output for the retrofit hub, and DC input/output for backup battery connection. This arrangement ensures simple installation and flexible system configuration.
Operating conditions
The device is designed for operation in a temperature range of -10 to +40 °C and relative humidity of 10 to 90% non-condensing. For storage, it is certified for -40 to +70 °C, ensuring long-term reliability.
Diagnostics and indication
Three status LED indicators provide immediate visual feedback on power status, battery charging, and output operation, facilitating system diagnostics and maintenance.
