Instant 802.3af Compatibility for Ubiquiti Devices

This adapter transforms almost any Ubiquiti 24V PoE device into a fully compliant 802.3af-compatible product. It delivers 48V PoE output at 0.5A, providing reliable power delivery to devices like UniFi access points or cameras that require standard PoE input. The Gigabit Ethernet interface ensures no bottleneck in network performance while maintaining full PoE functionality.

Compact Design with Built-in Surge Protection

Measuring just 30.3 mm x 95.5 mm x 30.3 mm and weighing 50 g, the INS-3AF-I-G fits easily into tight network enclosures or mounting spaces. The built-in 15 kV surge protection safeguards both the adapter and connected devices from electrical spikes, making it suitable for environments where voltage fluctuations are a concern. Its white finish blends unobtrusively with most networking equipment.

Plug-and-Play Network Integration

Installation requires no configuration—simply connect your 24V PoE device to the adapter’s output port and link the input to your 802.3af PoE switch or injector. The adapter automatically negotiates power delivery, eliminating compatibility headaches. Operating temperature range of 0-70°C ensures reliable performance in varied environments, from server rooms to outdoor installations with appropriate housing.

Frequently Asked Questions

Q: Can this adapter power any Ubiquiti device?

A: No, it only works with Ubiquiti devices designed for 24V PoE input.

Q: Does this provide power injection or just conversion?

A: It converts 802.3af PoE to 24V PoE for compatible devices, not power injection.

Q: What’s the maximum power output?

A: The adapter provides 0.5A at 48V, suitable for most small Ubiquiti devices.

Q: Is this weatherproof for outdoor use?

A: No, it requires indoor or protected installation; verify environmental ratings.

Q: Can I use this with non-Ubiquiti PoE devices?

A: Only if they specifically require 24V PoE input, not standard 802.3af devices.
