Convert Standard 802.3af PoE to 24V Passive Power for Legacy Ubiquiti Devices Outdoors
The Ubiquiti INS-3AF-O-G is an outdoor-rated inline adapter that converts standard 802.3af PoE (48V) from any compliant PoE switch into the 24V passive PoE that older Ubiquiti airMAX and UniFi devices require. It sits inline on the Ethernet cable between the PoE switch and the device, translating the power standard while passing Gigabit data through without interruption.
Many Ubiquiti devices from the airMAX and early UniFi lines use 24V passive PoE instead of the 802.3af/at standard. This adapter lets those devices run off a standard 802.3af PoE switch instead of a dedicated passive PoE injector, which simplifies deployments where the switch manages power for the entire network and individual injectors per device are impractical. The outdoor version is weatherproofed for pole-mount and mast installations.
Where the INS-3AF-O-G Fits
- Outdoor airMAX radio deployments on poles and masts where a standard 802.3af PoE switch powers the network and the radio requires 24V passive PoE
- Mixed-standard UniFi networks where some older APs need 24V passive power but the switch only outputs 802.3af, and replacing the APs is not in scope
- Remote power management where the PoE switch controls power cycling of outdoor devices, which passive injectors cannot do since they have no managed power state
What the INS-3AF-O-G Delivers
- 802.3af to 24V passive conversion: Accepts 48V 802.3af input and outputs 24V passive PoE at up to 500 mA. Compatible with most Ubiquiti 24V passive PoE devices.
- Gigabit passthrough: Full 10/100/1000 Mbps data passthrough on both input and output ports. No bandwidth bottleneck from the conversion.
- ±15kV surge and ESD protection: Built-in Ethernet isolation protects the connected device from electrical surges and static discharge common in outdoor installations.
- Outdoor rated: Weatherproofed for outdoor pole and mast installations where the adapter sits exposed to the elements alongside the device it powers.
