48V 0.5A PoE Adapter for Ubiquiti Devices

This 24W passive PoE injector supplies 48V DC at 0.5A to compatible Ubiquiti hardware. It accepts 90-260V AC input at 47-63 Hz and includes an AC cable with earth ground for surge protection and clamping protection against ESD events. The compact black enclosure measures 1.30" x 3.47" x 2.24" and weighs 0.30 lb.

Indoor Installers Needing Surge Protection

Network technicians deploying Ubiquiti access points or radios that require 48V passive PoE will benefit from the integrated earth grounding and maximum surge discharge features. Builders whose devices demand Gigabit Ethernet passthrough or higher current output should look elsewhere, as this model lacks a Gigabit LAN port and delivers only 0.5A.

48V DC Output Voltage at 0.5A

The adapter provides a fixed 48V DC output at 0.5A, yielding 24W of power. This specific voltage and current combination determines compatibility; devices requiring 15V, 24V or 50V inputs, or those needing more than 0.5A, cannot be powered by this unit.

Questions about this item

Which Ubiquiti devices can I power with the 48V 0.5A output from this adapter?

It powers Ubiquiti PoE devices that accept 48V DC at 0.5A passive PoE, such as compatible airMAX radios and UniFi access points.

Does the earth-grounding and surge protection function if I connect this adapter to a two-prong outlet?

The AC cable includes an earth ground pin; surge protection and ESD clamping require a properly grounded three-prong receptacle to operate as designed.

How can I confirm the adapter is delivering 48V DC at 0.5A after installation?

The unit has no built-in meter; verify operation by checking that the powered Ubiquiti device boots, links at expected speed, and reports stable voltage in its management interface.
