Ubiquiti 54V DC 80W Gigabit PoE Injector (POE-54V-80W)

Product Overview The Ubiquiti POE-54V-80W is a high-capacity external power injector designed to supply heavy-duty power and high-speed data to demanding network infrastructure. Delivering an output of 54V DC at 1.5A for an aggregate capacity of 80W, this unit provides raw, stable power over a 4-pair Ethernet system. It is purpose-built to drive power-intensive equipment—such as Ubiquiti EdgePoint routers, airFiber wireless backhaul links, and high-capacity multi-port switches—without introducing performance bottlenecks. Featuring a dedicated Gigabit LAN port, it ensures your data throughput remains uncompromised while shielding internal circuitry against external electrical faults.

Please Note: This injector uses passive 4-pair powering and does not follow the standard 802.3af/at protocol. Please check your specific hardware specifications to ensure absolute power compatibility before connection.

Key Features

• 80W Power Delivery: Outputs a reliable 54V DC at 1.5A, supplying the critical headroom needed for large enterprise deployment platforms and long-range wireless backhauls.

• Full Gigabit Data Speeds: Outfitted with a pass-through Gigabit RJ45 interface to maintain flawless backhaul transmissions and avoid throttling network performance.

• Industrial Device Protection: Built with integrated surge, clamping, and over-voltage protection arrays to actively defend sensitive backend chipsets against unexpected line spikes.

• Electrostatic Discharge Guarding: When combined with high-quality shielded Ethernet cabling and proper earth grounding, this adapter significantly lowers the risk of outdoor hardware failure caused by ESD.

• Robust 4-Pair Delivery: Implements efficient 4-pair power injection across pins 1, 2, 4, 5 (+) and 3, 6, 7, 8 (-) to minimize resistance losses over extended copper cable lengths.
