How to verify this is the right power supply
Frequently asked questions
Which power supply does the Ubiquiti USW-Ultra-210W use?
The USW-Ultra-210W is powered by an external 54V DC adapter (210W). The original Ubiquiti adapter can be replaced by any 54V DC adapter with the same barrel connector, correct polarity and at least the same wattage. The required connector is 5.5 × 2.1 × 11.5 mm barrel plug, polarity center-positive.
Can I use a power supply with a higher amperage rating?
Yes. The device only draws the current it needs. A higher amperage rating is safe. Never use a higher voltage.
Is this an original Ubiquiti power supply?
This is a compatible replacement adapter that meets or exceeds the original specifications, is CE-certified and tested before shipping. It is not manufactured by Ubiquiti.
