Power output

This 24V 0.5A PoE adapter powers compatible Ubiquiti passive PoE devices from a standard AC outlet. It delivers 12W through a single Ethernet port and includes earth grounding plus surge protection to guard against ESD events. The compact black enclosure measures 3.43" x 1.73" x 1.14" and weighs 0.20 lb. It operates on 100-240VAC at 50/60Hz with 75+% efficiency.

Upgrade path

It replaces a missing or failed injector for hardware that requires 24VDC at 0.5A. The step up is justified when a device needs the higher 24V rail instead of the 15V 0.8A alternative, or when surge protection and grounding are required for outdoor or exposed runs. Models with a Gigabit LAN port or 1.0A output are separate SKUs not covered by this adapter.

Build fit

The unit plugs directly into a wall socket or mounts with optional brackets, needing only an AC circuit and a Cat5e or better cable to the powered device. It frees the installer from running separate DC wiring to radios, bridges or the airGateway bridge. No Gigabit pass-through is provided, so throughput is limited to the device's own Ethernet capability.

Questions about this item

What are the exact dimensions for mounting this adapter on a wall?

The adapter measures 3.43 inches by 1.73 inches by 1.14 inches and weighs .20 lb, so it fits standard wall-mount brackets for the POE-24-12W model.

Which cable should I plug into the LAN port first to avoid a dead link?

Connect the Ethernet cable from your switch or router to the LAN port on the adapter, then run a second cable from the PoE port to the Ubiquiti device; reversing them leaves the remote unit unpowered.

When should I replace the adapter if surge protection degrades?

Replace the unit after any known lightning strike or ESD event that trips the clamping protection, as the surge components are sacrificial and not user-serviceable.
