Overview
The Ubiquiti POE-24-AF5X-US is a 24W PoE injector designed to provide DC power to compatible Ubiquiti network equipment over Ethernet cabling while passing Gigabit Ethernet data. The injector accepts 100–240VAC input and delivers 24VDC at up to 1A to the connected PoE device.
The POE-24-AF5X is specifically associated with Ubiquiti airFiber 5X equipment and is intended for compatible Ubiquiti devices requiring its 24V passive PoE power configuration. It should not be treated as a generic IEEE 802.3af PoE injector; compatibility with the connected device's required PoE voltage and pin configuration should be confirmed before deployment.
Power and Ethernet Connectivity
The injector provides a 24VDC output rated at 1.0A, giving a maximum rated output of 24W. Its Ethernet interface includes a Gigabit LAN port and a shielded RJ45 Data IN / PoE connection for delivering both network data and DC power over the Ethernet cable.
The AC input is rated at 100–240VAC at 50/60Hz. Ubiquiti specifies input current of 0.6A at 120VAC and 0.4A at 240VAC. The AC connection uses an IEC-320 C6 connector.
PoE Powering
The POE-24-AF5X uses four-pair powering. Ubiquiti specifies pins 1, 2, 4 and 5 as positive and pins 3, 6, 7 and 8 as negative. Two-pair powering is not specified for this model.
The 24W rating is the maximum rated DC output of the injector. The connected device must be designed to accept 24VDC passive PoE using the specified pin configuration. The injector should therefore be selected based on the exact power requirements of the target network device rather than by PoE wattage alone.
Protection
The injector incorporates difference-mode and common-mode surge protection, 11V data clamping protection, and 60V power clamping protection. Ubiquiti specifies maximum surge discharge of 1500A for 8/20 μs power surges and peak pulse current of 36A for 10/1000 μs data pulses.
The design also specifies less than 5 pF data shunt capacitance and a response time below 1 ns. These protection characteristics are intended to help protect connected network equipment against electrical surge and transient events.
Key Features
- 24VDC output at up to 1.0A for a maximum rated 24W output
- Gigabit Ethernet connectivity through the integrated LAN interface
- Four-pair PoE powering using the specified 1, 2, 4, 5 positive and 3, 6, 7, 8 negative pin configuration
- Difference-mode and common-mode surge protection with separate data and power clamping
- 100–240VAC, 50/60Hz input for use across supported AC electrical systems
Applications
The POE-24-AF5X is intended for deployments where a compatible Ubiquiti network device requires 24V passive PoE power and Gigabit Ethernet connectivity from a single Ethernet connection. It is particularly associated with Ubiquiti airFiber 5X equipment and should be deployed only with equipment confirmed to support the injector's voltage and PoE pin configuration.
DC Supplies Product Note
Verify the target device's exact PoE requirements before ordering this injector. The POE-24-AF5X supplies 24VDC using a four-pair pin configuration and is not specified by Ubiquiti as an IEEE 802.3af standard PoE injector. A device requiring a different PoE voltage, polarity, or pin assignment should use the appropriate power injector instead.

FAQs
What voltage does the POE-24-AF5X-US provide?
The injector provides 24VDC at up to 1.0A, for a maximum rated output of 24W.
Does this injector support Gigabit Ethernet?
Yes. Ubiquiti specifies a Gigabit LAN port and a shielded RJ45 Data IN / PoE interface.
Is the POE-24-AF5X an IEEE 802.3af PoE injector?
Ubiquiti's specifications identify the unit by its 24VDC passive power configuration rather than specifying IEEE 802.3af support. The connected device should therefore be confirmed as compatible with 24V passive PoE and the specified four-pair pin configuration.
Which Ethernet pins carry power?
The specified four-pair configuration uses pins 1, 2, 4 and 5 for positive power and pins 3, 6, 7 and 8 for negative power.
What AC input does the injector support?
The injector is rated for 100–240VAC at 50/60Hz. Ubiquiti specifies 0.6A input current at 120VAC and 0.4A at 240VAC.
What protection features are included?
The injector provides difference-mode and common-mode surge protection, 11V data clamping, 60V power clamping, up to 1500A maximum power surge discharge, and 36A peak data pulse current protection.
