The Ubiquiti POE-24-12W-G is a 24V Passive Gigabit Power over Ethernet (PoE) adapter.¹ It's designed to provide both electrical power and a data connection to a compatible device over a single Ethernet cable, simplifying installation and reducing cable clutter.²

Key Features and Specifications

• Voltage and Amperage: It provides a fixed 24V DC output with a maximum current of 0.5A.³

   

• Power: The adapter has a total power output of 12W (24V * 0.5A = 12W).

• Data Speed: It supports Gigabit Ethernet (10/100/1000 Mbps), ensuring that it doesn't create a bottleneck for high-speed network connections.⁴ The "G" in the model name stands for Gigabit.⁵

   

• PoE Type: It uses passive PoE, meaning it supplies a constant voltage without negotiating with the connected device.⁶ It's crucial to use this adapter only with devices that are specifically designed to accept a 24V passive PoE input. Using it with an incompatible device can cause damage.

   

• Compatibility: This adapter is a standard power source for many older Ubiquiti devices, including a wide range of airMAX and some UniFi access points.⁷

   

• Model Number: The "(EU)" indicates that this version is shipped with a European-style power cord. The "0.5A" also confirms the amperage.

This product is a simple and reliable solution for powering Ubiquiti's 24V passive PoE devices.
