The Instant PoE Adapter from Ubiquiti Networks, model INS-3AF-I-G, is a converter for indoor use that transforms PoE devices from the UniFi or airMAX brands into compatible 24-V PoE products. It enables the use of Ubiquiti devices featuring an 802.3af PoE input on networks that provide passive 24-V PoE power. The conversion is achieved by transforming the input power from 48 VDC to an output of 24 VDC with a maximum current of 0.5 A. This adapter is specifically designed for indoor use and features a compact design with a diameter of 30.26 mm and a height of 95.5 mm.

Applications
This adapter is suitable for networks using passive 24-V PoE systems, for example in security or surveillance systems where power is supplied via the network cable. It is ideal for integrating Ubiquiti devices into existing infrastructures that do not support active PoE technology.

Features and Equipment in Detail
The adapter includes two Gigabit RJ45 ports: one PoE input and one PoE output. The input receives power via 802.3af PoE, while the output provides passive 24-V PoE power. Power is supplied via pairs 4, 5+ and 7, 8 Return, which is typical for passive PoE technology. The maximum power consumption is 48 VDC at 0.5 A, with the output delivering 24 VDC at 0.5 A. The integrated Ethernet ESD/overvoltage protection provides protection of ±15 kV, enhancing reliability during operation.

Technology Explained Simply
The adapter functions as a PoE converter, transforming power from an active 802.3af standard (48 V) into a passive 24-V PoE standard. This is particularly useful when Ubiquiti devices are deployed in systems that do not offer active PoE support. Passive PoE technology uses pairs 4, 5+ and 7, 8 Return to transmit voltage, enabling simple integration into existing networks. The Gigabit Ethernet interface ensures a data transfer rate of up to 1000 Mbit/s, ensuring network performance is not compromised.

Compatibility and Accessories
The adapter is compatible with Ubiquiti UniFi and airMAX devices that feature an 802.3af PoE input. It is not designed for other manufacturers or PoE standard variants unless they meet the specified input and output conditions.

Installation and Mounting
Installation is performed by simply connecting the adapter between the PoE network and the Ubiquiti device. The input is connected to a PoE source, and the output is connected to the device to be powered. No additional tools or configurations are required. The operating temperature ranges from 0 °C to 70 °C, allowing use under typical indoor conditions.

Operational Advantages
Using the Instant PoE Adapter enables flexible integration of Ubiquiti devices into existing networks without requiring additional power supplies. Passive PoE technology reduces installation complexity, as no special PoE switches are needed. The integrated overvoltage protection increases safety and extends the device’s lifespan. The compact design and low weight of 50 g facilitate placement and mounting.
