Ubiquiti POE-24-30W-US – 24V DC 30W Gigabit Passive PoE Injector
Overview
The Ubiquiti POE-24-30W-US is a Gigabit 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 rather than standard IEEE 802.3af/at active PoE, including select airMAX, airFiber, EdgeMAX, mFi, UniFi AP, and UniFi Video products [citation:15][citation:8]. The injector simplifies deployment by eliminating the need for a separate power outlet at the device location [citation:19].
Power and Data Delivery
The injector outputs 24V DC at up to 1.25A for a total power budget of 30W [citation:9][citation:15]. It supports Gigabit Ethernet (10/100/1000 Mbps) throughput across both its LAN and PoE ports, ensuring the injector does not become a bandwidth bottleneck in high-throughput deployments [citation:9][citation:19]. Power is delivered using 4-pair powering with positive on pins 1, 2, 4, 5 and negative on pins 3, 6, 7, 8 [citation:9].
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 and 36A (10/1000 µs) for data [citation:9]. When used with Ubiquiti TOUGHCable, the injector provides earth grounding and protection against electrostatic discharge (ESD) events [citation:8][citation:14].
Compatibility
This injector is compatible with Ubiquiti devices that accept passive 24V PoE. It is designed for use with airMAX, airFiber, EdgeMAX, mFi, UniFi AP, and UniFi Video / airVision products [citation:15]. It is NOT compatible with devices that require standard IEEE 802.3af/at active PoE, such as the UniFi U6-LR, which requires 44–57V DC input [citation:15].
The US version includes a power cable suitable for North American AC outlets and an IEC-320 C6 AC connector [citation:9].
Key Features
- 24V DC passive PoE output at up to 30W total power [citation:9]
- Gigabit Ethernet LAN and PoE ports for full 10/100/1000 Mbps throughput [citation:9]
- Built-in surge protection with difference and common mode clamping [citation:9]
- Compact desktop form factor with 94 × 60 × 33 mm dimensions [citation:9]
- Shielded RJ45 sockets for data IN and PoE out [citation:9]
Applications
The POE-24-30W-US 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 in point-to-point wireless links, small network installations, and retrofit scenarios where adding a PoE switch is impractical [citation:8][citation:19]. The injector is suitable for indoor use with an operating temperature range of 0 to 40°C [citation:9].
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—connecting a device that expects active PoE (such as 48V) to this injector may damage the device [citation:15]. The POE-24-30W-US does not include mounting brackets; the 24V 0.5A models (POE-24-12W/POE-24-12W-G) are wall-mountable using optional brackets [citation:14].

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. Using it with a device that requires active 48V PoE may cause damage [citation:15].
What devices can I power with this injector?
Compatible Ubiquiti devices include many airMAX, airFiber, EdgeMAX, mFi, UniFi AP, and UniFi Video products that specify 24V passive PoE input [citation:15].
Does this injector support Gigabit speeds?
Yes. Both the LAN and PoE ports are Gigabit RJ45 sockets, supporting 10/100/1000 Mbps Ethernet [citation:9][citation:19].
What is included in the box?
The package includes the POE-24-30W-US PoE injector and a power cable [citation:19].
