Overview
The Ubiquiti POE-48-24W-WH is a 48V DC, 24W PoE adapter designed to provide power and Ethernet connectivity to compatible PoE devices. It accepts 100–240V AC input and delivers 48V DC at 0.5A through a shielded RJ45 PoE connection.
Power Delivery
The adapter provides 48V DC at 0.5A, corresponding to a 24W output rating. Power is delivered using 2-pair PoE on pins 4 and 5 positive and pins 7 and 8 negative. The adapter does not support 4-pair powering.
Protection
POE-48-24W-WH incorporates differential-mode and common-mode surge protection, with 11V data clamping and 60V power clamping. Ubiquiti specifies a maximum power surge discharge of 1500A for an 8/20 μs waveform and a peak data pulse current of 36A for a 10/1000 μs waveform.
Connectivity
The adapter uses a shielded RJ45 socket for the data input and PoE output connection. The POE-48-24W-WH does not include a Gigabit LAN port or LAN activity indicator.
Key Features
- 48V DC at 0.5A PoE output
- 24W output power rating
- 2-pair PoE using pins 4, 5 and 7, 8
- Differential-mode and common-mode surge protection
- 100–240V AC universal input
Applications
The POE-48-24W-WH is intended for powering compatible Ubiquiti PoE equipment from a standard AC power source where a 48V, 24W PoE adapter is required. Verify the connected device's voltage, power, and PoE requirements before installation.
DC Supplies Product Note
This model is the non-Gigabit version of Ubiquiti's 48V 24W PoE adapter family. The exact POE-48-24W-WH model provides no Gigabit LAN port and uses 2-pair powering, so it should not be substituted with the visually similar POE-48-24W-G variant when those specifications matter.
