Ubiquiti INS-3AF-USB 802.3af to Usb Adapter

Product Description

The UBIQUITI INS-3AF-USB is a compact inline adapter that converts 802.3af Power over Ethernet (PoE) to USB power. It draws power directly from a PoE-enabled network switch or injector and delivers it through a USB output, eliminating the need for a separate power supply at the device end. This adapter is well suited for network installers and IT professionals who need to power USB devices in locations where only a PoE infrastructure is available. Installation is straightforward and requires no additional tools beyond the existing network cabling.

This adapter fits into network environments where 802.3af PoE is already deployed and a USB-powered device needs to be added at the same location. Typical use cases include powering small USB peripherals, sensors, or accessories in commercial or light industrial settings where running a separate AC power circuit is not practical. It is sold as a single unit and installs inline on a standard Ethernet run.

Key Features

• Converts 802.3af PoE input to USB power output
• Inline form factor requires no additional enclosure or mounting hardware
• Eliminates the need for a local AC power supply at USB device locations
• Single-unit package suitable for individual deployment or larger rollouts

Compatibility

Designed for use with 802.3af-compliant PoE switches and injectors in standard Ethernet network installations.

Installation Notes

Installation should be performed by a qualified network technician or licensed low-voltage installer familiar with PoE systems. Verify that the upstream switch or injector is 802.3af compliant and that the port budget is sufficient before connecting the adapter. Power down or disable the PoE port on the switch before making or removing connections to avoid potential damage to connected devices. Follow applicable local codes and NEC guidelines for low-voltage wiring.
