The Lifeline for Your Proven Ubiquiti Devices
The Ubiquiti POE-24-12W is more than just a Power Supply. It is the tailored Power Supply that keeps your proven Ubiquiti devices running. Specifically developed for products like the airMAX ac Components or older UniFi Access Points that require 24V passive PoE, this injector precisely and reliably delivers the energy they need for stable operation. It transforms a standard data line into a combined power and data highway, making it one of the essential PoE Injectors / Power Supplies for any professional setup with appropriate hardware.
Robust Protection Against Overvoltage and ESD
Especially in outdoor installations, Network components are susceptible to overvoltages and electrostatic discharges. Ubiquiti designed the POE-24-12W precisely for this. With an integrated overvoltage and clamping voltage protection, it shields your valuable equipment. The grounding option, ideally in combination with Ubiquiti TOUGHCable™, provides first-class Lightning Protection and safely dissipates harmful discharges before they can reach your devices. This is also relevant for Cabling. Thus, you invest not only in power but also in the longevity of your entire Network.
Thoughtful Details: Remote Reset and Compact Design
Sometimes it's the small things that make the biggest difference. The Remote Reset Functionality is one such detail. An Access Point mounted on a roof cannot simply be restarted. With the reset button on the injector, you can conveniently reset the connected device to factory settings from the technical room. This saves time, effort, and nerves. Thanks to its compact design and the option for wall mounting, this Ubiquiti Accessories item can also be discreetly and cleanly integrated into any existing Cabling.
Important Note: Passive PoE and Fast Ethernet
This injector uses passive PoE. This means the 24V voltage is permanently applied without any negotiation with the end device. Therefore, please only connect compatible devices! Connecting a laptop or a modern 48V PoE device can permanently damage it. Also note that this basic model is limited to 10/100 Mbps Fast Ethernet. For higher speeds, consider using suitable Ethernet Switch. For Gigabit speeds, you will need the sister model POE-24-12W-G. However, for many older devices, the 100 Mbps connection does not represent a bottleneck.

Frequently Asked Questions (FAQ)
What does 'passive PoE' mean for the POE-24-12W?
'Passive' means that the PoE Injector constantly applies 24V voltage to the Ethernet Cable wires without first checking if the connected device requires or can tolerate this voltage. In contrast, active PoE standards (like 802.3af/at) communicate with the end device to negotiate the required power before electricity flows, ensuring proper Network operation.
Which devices can I power with the Ubiquiti POE-24-12W?
This model is specifically designed for older Ubiquiti Networks products that require 24V passive PoE. These include many devices from the airMAX series (e.g., NanoStation M, Loco M), airGateway, and early versions of UniFi Access Points (e.g., UAP, UAP-LR before 2017). It is essential to check compatibility in the end device's datasheet before connecting any PoE Injectors / Power Supplies.
How does the reset button on the PoE injector work?
The small, recessed reset button can be pressed with a pointed object (e.g., a paperclip). If the connected Ubiquiti Networks device supports 'Remote Reset', holding the button for approximately 10 seconds will trigger a factory reset of the end device, without needing physical access to the device itself. This is a common feature for PoE Injectors / Power Supplies.
Can I use the POE-24-12W for a new UniFi U6 camera or a new Access Point?
No, absolutely not. Newer Ubiquiti Networks devices, especially the UniFi series from around 2017 onwards, typically use active 48V PoE (802.3af/at/bt). Connecting this 24V passive PoE Injectors / Power Supplies would not power these devices and could potentially damage them, including modern IP Cameras and UniFi Access Points.
Why does my device only get a 100 Mbps connection, even though it's capable of Gigabit?
You are likely using the POE-24-12W model and not the POE-24-12W-G model. Only the '-G' variant features Gigabit-capable ports. The standard model physically limits the data connection over Ethernet Cables to 100 Mbps, impacting your overall Network speed.
Is a power cable included?
Yes, typically a suitable AC power cable (power cord) with the country-specific plug is included with these Accessories. The connector on the device itself for the PoE Injectors / Power Supplies is an IEC-320 C6 plug.
