Stable 48V Power Supply for your Network
The Ubiquiti POE-48-24W is the professional solution for reliably powering compatible end devices. As a dedicated PoE Adapter 48V 24W, it ensures that your Access Points, IP Cameras, or WiFi Bridge Sets receive a constant and clean voltage. Especially in installations where high availability is crucial, this PoE Injectors / Power Supplies ensures smooth operation. It is the ideal choice for many Ubiquiti airMAX ac Components and other Ubiquiti devices that explicitly require a passive 48V power source. Forget unstable power supplies and rely on a proven solution from Ubiquiti.
Integrated Device Protection: More Than Just Power
Your Network hardware is an investment. The POE-48-24W helps you protect it. It features comprehensive Lightning Protection against overvoltage and electrostatic discharge (ESD). Especially with longer Cabling runs or installations in demanding environments, harmful voltage spikes can occur. This PoE Injectors / Power Supplies intercepts them before they reach your expensive end device. For optimal protection, especially crucial surge protection, you should always use shielded Ethernet Cables (STP) with the injector to ensure grounding via the power cable.
Flexible Installation Without Cable Clutter
The greatest strength of Power over Ethernet is the simplification of Cabling. With this PoE Injectors / Power Supplies, you only need a single Ethernet Cables to supply your device with data and power. This makes you incredibly flexible in choosing the mounting location and significantly reduces installation effort. The compact design of the injector allows for discreet placement. It belongs to the category of indispensable PoE Injectors / Power Supplies that should not be missing in any well-planned Network.
Important Note: Use Passive PoE with Caution
It is crucial to know that this is a passive PoE Injectors / Power Supplies. This means it permanently applies 48V to the line without first checking if the connected device can handle it. If you accidentally connect a non-PoE device, such as a laptop or a desktop Ethernet Switch, its Network port can be damaged. Therefore, always carefully check the technical specifications of your end device before connecting. This model is also limited to 10/100 Mbps. For Gigabit speeds, you need the sister model POE-48-24W-G.

Frequently Asked Questions (FAQ)
Is the POE-48-24W compatible with every PoE device?
No. This is a passive 48V PoE Injector. It is only compatible with devices that explicitly support 48V passive PoE as a power source. Connecting it to devices that require a different voltage standard (e.g., 24V passive) or an active PoE standard (802.3af/at) can damage the device. For various PoE Injectors / Power Supplies, ensure compatibility with your Network devices.
What is the difference between the POE-48-24W and the POE-48-24W-G?
The main difference lies in the supported Network speed. The POE-48-24W is limited to 10/100 Mbps (Fast Ethernet), while the POE-48-24W-G supports speeds up to 1000 Mbps (Gigabit Ethernet). Both deliver 48V and 24W of power, suitable for various Ethernet applications.
Can I power a Ubiquiti UniFi 6 Pro Access Point with this injector?
No, generally not. The UniFi 6 Pro (U6 Pro) requires active 48V, 802.3af PoE. This injector provides passive 48V PoE. Although the voltage is similar, the negotiation required for the 802.3af standard between the PoE Injector and the device is missing, which can lead to incompatibility or damage. For Ubiquiti Networks UniFi Access Points, always check the specific PoE Injectors / Power Supplies requirements.
Do I need a special Ethernet Cable for this PoE Injector?
For optimal performance and especially to ensure ESD protection, the use of shielded twisted-pair Cabling (e.g., Cat5e or higher, STP) is recommended. An unshielded cable (UTP) will work, but it does not provide protection against electrostatic discharge. Proper Ethernet Cables are crucial for reliable PoE Injectors / Power Supplies operation.
Does the injector have an LED indicator for status checking?
No, this specific model does not have a LAN activity or status LED. The operational status can only be checked by the function of the connected end device within your Network.
Can I use the injector outdoors?
