Power delivery for EdgePoint switches

The Ubiquiti Networks POE-54V-80W is a 54 V DC Power over Ethernet injector rated at 80 W. It supplies power to compatible EdgePoint devices such as the EP-R8 and EP-S16 through a single Gigabit Ethernet connection while accepting 120 V or 230 V AC mains input.

Suited for Ubiquiti EdgePoint deployments

Network administrators who need to power an EdgePoint switch or remote radio from a standard AC outlet will find this injector matches the required voltage and wattage. Installations that require PoE+ at lower voltages, multi-port injection, or passive PoE on non-Ubiquiti hardware should look elsewhere.

54 V DC at 1.5 A output specification

The injector delivers a maximum of 54 V DC at 1.5 A, totalling 80 W, through its 10/100/1000Base-T output port. This exact voltage and current rating determines whether the unit can power a specific EdgePoint model, so verify the target device’s power requirements before purchase.

Questions about this item

How do I install the POE-54V-80W injector and what step is often missed?

Connect AC power using the supplied earthed cable, link your network to the 10/100/1000Base-T input port, then run the PoE output to the EdgePoint device; the step often missed is ensuring the AC earth ground is properly connected for surge protection.

What maintenance or replacement will the POE-54V-80W need over time?

The unit has no user-serviceable parts or replaceable fuses; maintenance is limited to checking the AC cable and connections periodically, and replacing the entire injector if surge protection components degrade after a major event.

What limit appears first when the POE-54V-80W runs continuously at full load?

The 80 W / 54 V DC 1.5 A output ceiling is the first hard limit; sustained draw at that level relies on passive cooling within the 123 x 65 x 34 mm enclosure, so thermal throttling or shutdown can occur if airflow is restricted.
