The Bridge Between Old and New: Operating 24V Devices with 802.3af PoE
Do you use proven Ubiquiti hardware like airMAX ac Components or older UniFi Access Points that require 24V passive PoE, but your new Ethernet Switch only provides the modern 802.3af PoE standard with 48V? The Ubiquiti INS-3AF-I-G is the ingenious and cost-effective solution for exactly this problem. Instead of replacing your entire infrastructure, simply connect this compact converter in between. It safely and reliably converts the 48V into 24V passive PoE, ensuring your devices continue to run smoothly within your Network.
Central Management & Longer Cable Runs
One of the biggest advantages of using this PoE converter for long Cable runs is the centralization of your Power Supply. You no longer need a separate power outlet at the device's mounting location. More importantly, you can conveniently restart (power-cycle) the connected device at any time via the web interface of your PoE Switch. This saves time and effort during maintenance. Additionally, the higher input voltage of 48V enables a more stable Power Supply over long distances, as power loss along the cable path is minimized.
Integrated Protection for Your Valuable Hardware
The INS-3AF-I-G is more than just a voltage converter. It also acts as an additional protective layer for your connected devices. With integrated ±15kV ESD/EMP protection, it shields sensitive electronics in IP Cameras or Access Points from damage due to electrostatic discharges or voltage spikes. This is a small detail with a big impact, increasing the lifespan and reliability of your entire Network and is considered an important Ubiquiti Accessories item.
Plug & Play: It Couldn't Be Easier
Forget complicated configurations or software installations. The Ubiquiti Instant 802.3af Adapter is a true Plug-and-Play device. You plug the Ethernet Cables from the PoE Switch into the 'PoE In' port and the cable to the end device into the 'PoE Out' port – done. The converter is operating system independent and works at the physical layer of the Network without affecting data transmission. There is no faster or simpler method to convert passive PoE to 802.3af.

Frequently Asked Questions (FAQ)
Can I operate a 24V device with the INS-3AF-I-G on a 48V PoE+ Switch?
Yes, this is the primary purpose of this PoE Injectors / Power Supplies converter. It takes the 48V from the 802.3af-compliant PoE or PoE+ Ethernet Switch and safely converts it into the 24V passive PoE required for the end device.
Does the converter also work with devices from other manufacturers?
Primarily, the converter is optimized for Ubiquiti Networks products such as airMAX ac Components or UniFi Access Points. However, it can theoretically work with any device that requires 24V passive PoE via pin assignment 4, 5 (+) and 7, 8 (-) and consumes no more than 12 watts. Compatibility should be checked in the end device's datasheet beforehand.
Does the adapter reduce the speed of my Gigabit connection?
No, the INS-3AF-I-G is designed for Gigabit speeds and does not affect the data transfer rate of 10/100/1000 Mbps. It operates transparently at the Network data level and only influences the Power Supply of your Ethernet Switch.
What is the difference between the INS-3AF-I-G and the INS-3AF-O-G?
The main difference is the place of use. The 'I' in INS-3AF-I-G stands for 'Indoor'. The 'O' in INS-3AF-O-G stands for 'Outdoor' and features a weatherproof Enclosures. Technically, both fulfill the same conversion function, often used with various Mounting Systems.
Do I need special software for installation?
No, the PoE Injectors / Power Supplies converter is a pure 'Plug-and-Play' hardware device. No software installation or configuration is necessary. It is simply plugged between the Ethernet Switch and the device to be powered.
Why should I use this converter instead of a simple 24V power supply?
A PoE Injectors / Power Supplies converter offers two crucial advantages over a separate power supply: It eliminates the need for an additional power outlet at the installation site and allows remote restarting of the device via the Ethernet Switch's software.
