UBIQUITI NETWORKS INS-3AF-O-G Ubiquiti Instant 8023af Adapter, Outdoor, Gigabit content_copy

The Instant PoE Adapter from Ubiquiti Networks, model INS-3AF-O-G, is a specialised converter that transforms PoE-capable devices from Ubiquiti product families UniFi and airMAX into compatible 24-V-PoE devices. It enables the use of these devices in networks that support passive 24-V-PoE (Power over Ethernet) without requiring additional power supplies or network switches with special PoE technology. The device is designed for outdoor use and features a robust construction that meets the requirements of industrial and outdoor installations.

Applications

The adapter is primarily designed for integrating Ubiquiti PoE devices into existing or newly constructed networks based on passive 24-V-PoE. This includes applications in industrial communication, smart city environments, surveillance systems, or wireless infrastructure, where power supply via Ethernet cable is required. Its suitability for outdoor use is ensured by an operating temperature range of -30 to 70 °C, enabling functionality under extreme climatic conditions.

Functions and Equipment in Detail

The adapter features a PoE input that receives a voltage of 48 VDC at a current of 0.5 A. This input is compatible with standard PoE networks, such as those provided by Ubiquiti switches or other PoE sources. The PoE output delivers a voltage of 24 VDC at a maximum current of 0.5 A, matching the specification for passive 24-V-PoE. Power is supplied via pairs 4, 5 (positive polarity) and 7, 8 (return), in accordance with common conventions for passive PoE systems. The device is equipped with a Gigabit RJ45 port, enabling data transmission at speeds up to 1 Gbit/s. Additionally, a 20 cm long Gigabit Ethernet cable is included in the delivery, intended for connecting the adapter to the target device.

Technology Explained Simply

The adapter acts as a power and signal converter between an active PoE network (48 V) and a passive 24-V-PoE system. It converts the received PoE power supply from 48 VDC to a 24-VDC power supply, which is transmitted to the connected Ubiquiti device via the Ethernet cable. Data transmission occurs over the same cable, with Ethernet ESD and overvoltage protection rated at ±15 kV safeguarding the devices against electrical disturbances and overvoltages. This protection function is particularly important in outdoor environments, where lightning strikes or electrical discharges may occur.

Compatibility and Accessories

The adapter is specifically developed for Ubiquiti PoE devices from the product lines UniFi and airMAX. It enables the use of these devices in environments that support passive 24-V-PoE. The included 20 cm long Gigabit Ethernet cable is intended for direct connection between the adapter and the connected device.

Mounting and Installation

Installation is performed by simply connecting the adapter to a PoE-capable network via the PoE input, and then connecting the Ubiquiti device using the included RJ45 cable at the PoE output. Dimensions are Ø 30.2 mm x 166 mm without cable, and Ø 30.2 mm x 366.6 mm with cable.

Operational Advantages

Using the Instant PoE Adapter reduces the number of required components in a PoE infrastructure, as no additional power supplies or special switches are needed. Integration is quick and requires no additional configuration. The ESD and overvoltage protection function increases system reliability, especially in critical outdoor applications. The operating temperature range of -30 to 70 °C ensures stable performance under extreme environmental conditions.
