The Power Hub for your Ubiquiti Network
Do you want to power your Ubiquiti hardware professionally and securely? The POE-48-24W-G is more than just a Power Supply. It is a specialized PoE Injector designed to intelligently combine power and data over a single Ethernet Cable. Forget unsightly power strips and separate power cables at the mounting location of your UniFi Access Points or IP Cameras. With this adapter, you create a clean, efficient, and powerful installation that makes your entire Network more reliable.
Gigabit Performance without Compromise
Many cheaper PoE Adapters limit the data rate to 100 Mbps. Not so the POE-48-24W-G. With its Gigabit RJ45 ports (10/100/1000 Mbps), it ensures that the full bandwidth of your Network reaches the end device. This is crucial for modern UniFi Access Points that provide high data rates for many clients, or for high-resolution IP Cameras from the UniFi Protect series. Your performance will not be hampered by the Power Supply.
Integrated Shield for your Hardware
A power outage or voltage spike in the grid can quickly destroy expensive hardware. Ubiquiti has therefore equipped the POE-48-24W-G with robust protection mechanisms. The integrated overvoltage protection (differential and common mode) and protection against electrostatic discharge (ESD) act like a bodyguard for your connected devices. Grounding via the included AC cable safely dissipates harmful energy before it reaches your equipment. An investment that pays off, offering essential Lightning Protection.
Important Note: Understanding Passive PoE
This PoE Injector uses passive PoE. This means it constantly delivers 48V as soon as it is plugged in. This is perfect for all devices that are designed precisely for this. Please check your device's datasheet before connecting to ensure it supports 48V Passive PoE. Connecting to an incompatible device (e.g., one that expects the active 802.3af/at standard) can lead to damage. If you are unsure, we are here to help – a quick inquiry protects your investment. You can find such specialized components in our category for PoE Injectors / Power Supplies.

Frequently Asked Questions (FAQ)
Is the POE-48-24W-G compatible with all UniFi Access Points?
No, it is only compatible with UniFi Access Points and other Ubiquiti Networks devices that explicitly require 48V passive PoE. Newer devices often use the 802.3af/at (active PoE) standards. It is essential to check the datasheet of the device to be powered.
What is the difference between passive and active PoE (802.3af/at)?
Passive PoE, as used by this injector, constantly sends a fixed voltage (here 48V) over the Ethernet Cable. Active PoE (IEEE 802.3af/at standard), on the other hand, performs a "handshake" where the power sourcing equipment checks if the end device is PoE-capable and what voltage it requires before releasing power.
Can I use this injector outdoors?
No, the POE-48-24W-G is designed exclusively for indoor use. The operating temperature and humidity specifications are not suitable for outdoor deployment.
Does the injector supply power and data over a single cable?
Yes, that is its main function. You connect your non-PoE Ethernet Switch to the "LAN" port and the device to be powered to the "POE" port. The injector then mixes the data with the power and sends both over a single Ethernet Cable to the end device.
Why doesn't the injector have a reset button?
This model is designed as a pure PoE Injectors / Power Supplies unit and does not offer advanced functions like a remote reset. To restart the connected device, the injector must be disconnected from the Power Supply.
Is a power cable included?
Yes, typically a suitable AC power cable with protective earthing is included for safe operation.
