Product Description
The 54V 3.9A 210.6W AC/DC Power Adapter is a high-output replacement power supply designed for compatible Ubiquiti UniFi switches and PoE networking equipment requiring 54V DC power.

It is ideal as a replacement for a lost, damaged or failed power supply, or as a spare adapter for enterprise, office, home lab, networking and PoE installations.
