Stable 24V Power Supply for your Ubiquiti Network
The Ubiquiti POE-24-24W is the foundation for a reliable Power Supply for your Network components. It was precisely developed to feed a stable 24V DC voltage into your Ethernet Cable. This is ideal for powering a variety of Ubiquiti devices such as older UniFi Access Points or airMAX ac Components.
Forget searching for a free power outlet on the ceiling or an exterior wall. With this PoE Injector, you only need a single Cabling for data and power, making installation cleaner, faster, and more flexible.
Maximum Device Protection: More Than Just a Power Supply
This injector is far more than a simple power supply. Ubiquiti has integrated a comprehensive protection mechanism here that shields your connected devices from the most common dangers.
Advanced Lightning Protection and ESD (electrostatic discharge) protection intercepts voltage spikes before they can reach your expensive IP Cameras or WiFi Access Points. For maximum protection, it is crucial to operate the injector with the supplied grounded power cable and ideally use shielded Ethernet Cables. This creates a secure environment, especially for outdoor installations.
The Ingenious Remote Reset Function of the POE-24-24W
Every administrator knows the problem: a device mounted high on a mast or under an eaves is no longer responding. Instead of climbing a ladder, the POE-24-24W offers an ingenious solution. It features a small but extremely useful reset button. Pressing it briefly interrupts the power supply to the end device and restarts it. This feature is a decisive advantage in maintenance and saves you valuable time and effort when a connected device requires a restart.
Passive PoE Explained: What You Absolutely Need to Know
It is important to understand that this injector uses passive Power over Ethernet. Unlike active PoE standards (such as 802.3af/at), passive PoE constantly sends 24V over the cable without first checking if the connected device is compatible. Therefore, never connect a non-PoE device such as a laptop or a desktop PC to the 'POE' port, as this can damage the Network card.
Always check the specifications of your end device before purchasing. If it requires 24V passive PoE, this injector from the PoE Injectors / Power Supplies category is the perfect choice for you.

Frequently Asked Questions (FAQ)
How is the Ubiquiti POE-24-24W correctly connected?
Connect an Ethernet Cable from your Router or Ethernet Switch to the "LAN" port of the PoE Injector. Then connect a second Ethernet Cable from the "POE" port of the Injector to the end device (e.g., a WiFi Access Point). Finally, connect the power cable to the Injector and a power outlet.
Can I use this PoE Injector for any PoE device?
No, absolutely not. This PoE Injector provides 24V passive PoE. It is only suitable for devices that explicitly require this standard. Connecting it to devices that need 48V or the 802.3af/at standard will not work and can damage the device.
What is the difference between the POE-24-24W and the POE-24-24W-G?
The main difference is the data speed. The POE-24-24W supports Fast Ethernet (10/100 Mbit/s), while the POE-24-24W-G supports Gigabit Ethernet (1000 Mbit/s). For devices with a Gigabit connection, the G-variant is essential to utilize full speed.
Why is grounding so important for this PoE Injector?
Grounding via the three-pin power cable and the use of shielded Ethernet Cables (STP) are crucial to make the built-in protection mechanisms against ESD (electrostatic discharge) and overvoltage effective. This is particularly critical for outdoor installations of IP Cameras or WiFi Access Points.
My device does not power on with the PoE Injector. What can I do?
First, check if your device is compatible with 24V passive PoE. Then, test with another known-working Ethernet Cable. Ensure that the cables are firmly seated in the ports. If the device still does not receive power, the PoE Injector or the device itself might be defective.
Can I operate a 24V/0.5A device with this 24V/1A PoE Injector?
Yes, that is certainly possible. The end device only draws as much current (amperes) as it needs. As long as the voltage (24V) matches and the PoE Injector can supply at least the required current (here 0.5A), operation is safe.
