Authentic 12W Ruckus power adapter

This genuine Ruckus Wireless AC adapter supplies 12 volts at 1 amp for compatible ZoneFlex access points. It accepts a universal 100-240 volt input at 50-60 Hz. The barrel connector measures 5.5 by 2.1 mm and matches the original equipment specification.

Thermals and power draw

Built-in safeguards protect against incorrect voltage, short circuit and internal overheating. The unit draws 0.4 amps on the AC side while delivering a steady 12 watts to the access point. No fan is present, so operation remains silent in normal use.

What the OEM design changes

Genuine construction uses quality materials that meet Ruckus safety standards for the R310, R320, R500 and R600 models. The protection features reduce the risk of damage to the connected device. Buyers needing a different voltage, higher wattage or alternative connector size should look elsewhere.

Questions about this item

How do I connect the 5.5 x 2.1 mm barrel plug to my Ruckus ZoneFlex R310 access point?

Align the 5.5 mm outer diameter and 2.1 mm inner pin with the R310 DC jack, then push straight in until the connector seats firmly; forcing it at an angle can bend the centre pin.

Will the internal overheating protection circuit need replacement after extended use?

The built-in safeguards against internal overheating, short circuit and incorrect voltage are non-replaceable solid-state features; if the adapter fails, the entire unit must be replaced.

At what input voltage does the adapter draw its maximum 0.4 A current?

The 0.4 A input rating occurs at the low end of the 100-240 V range, so sustained operation at 100 V will show the highest current draw.
