Ubiquiti POE-24-12W – 24V DC 12W Passive PoE Injector
Overview
The Ubiquiti POE-24-12W is a compact passive Power over Ethernet injector that combines data and 24V DC power onto a single Ethernet cable. It is designed for Ubiquiti devices that require passive 24V PoE, including select airMAX, airGateway, and other compatible products. The injector simplifies deployment by eliminating the need for a separate power outlet at the device location .
Power and Data Delivery
The injector outputs 24V DC at up to 0.5A for a total power budget of 12W . It supports standard Ethernet (10/100 Mbps) throughput across its LAN and PoE ports. Power is delivered using 2-pair powering with positive on pins 4, 5 and negative on pins 7, 8 .
Surge Protection
Ubiquiti PoE adapters include built-in surge protection features including difference and common mode protection, clamping protection rated at 11V for data and 60V for power, and a maximum surge discharge of 1500A (8/20 µs) for power . When used with Ubiquiti TOUGHCable, the injector provides earth grounding and protection against electrostatic discharge (ESD) events .
Compatibility
This injector is compatible with Ubiquiti devices that accept passive 24V PoE. It is designed for use with airMAX and airGateway products that specify 24V passive PoE input . The POE-24-12W works with the airGateway to bridge airMAX connections to Wi-Fi at customer locations .
This model does not include a Gigabit LAN port. For Gigabit support, the POE-24-12W-G variant is required .
Key Features
- 24V DC passive PoE output at up to 12W total power
- 2-pair powering on pins 4, 5 (+) and 7, 8 (-)
- Built-in surge protection with difference and common mode clamping
- Compact desktop form factor with 87 × 44 × 29 mm dimensions
- Remote reset capability and physical reset button
Applications
The POE-24-12W is used to power Ubiquiti access points, radios, and other passive 24V PoE devices where a PoE switch is not available or where a single-port injector is more cost-effective. It is commonly deployed with airMAX CPEs, airGateway units, and small network installations . The injector is suitable for indoor use with an operating temperature range of 0 to 40°C .
DC Supplies Product Note
This injector provides passive 24V PoE, not active IEEE 802.3af/at PoE. Verify that your device requires 24V passive PoE before purchase. The POE-24-12W does not include a Gigabit LAN port—if your deployment requires Gigabit throughput, select the POE-24-12W-G model instead. This model is wall-mountable using optional wall-mount brackets, which are not included .

FAQs
Is this the same as a standard PoE injector?
No. This is a passive 24V PoE injector, not an active IEEE 802.3af/at PoE injector. It delivers 24V DC power regardless of device negotiation. Verify your device requires 24V passive PoE before use.
Does this injector support Gigabit speeds?
No. The POE-24-12W does not include a Gigabit LAN port and supports standard 10/100 Mbps Ethernet. For Gigabit support, select the POE-24-12W-G model .
What devices can I power with this injector?
Compatible Ubiquiti devices include select airMAX CPEs and airGateway units that specify 24V passive PoE input . It works with the airGateway to bridge airMAX connections to Wi-Fi .
What is included in the box?
The package includes the POE-24-12W PoE injector and a power cable.
