AA20R-480A-R Description

Short technical summary and product information.

The Phihong USA AA20R-480A-R is a 48V, 20W AC/DC wall mount adapter designed for a wide range of electronic devices. It accepts a universal AC input from 90 to 264VAC at 47-63Hz, making it suitable for global use. The adapter provides a regulated 48V DC output at up to 0.42A with ±5% regulation and low ripple and noise of 480mV P-P maximum.

 

This adapter meets DoE Level VI efficiency standards and complies with Ecodesign/ErP Lot 7 (EU) 2019/1782 and CoC Version 5 Tier 2 requirements. It is certified to IEC 62368-1 safety standard and features Class II double insulation, eliminating the need for an earth ground connection. Protection features include over-voltage protection (<62Vpk), over-current protection with auto restart, and short circuit protection.

 

The wall mount form factor measures 72.5mm x 50.8mm x 33.25mm and weighs 146g. It comes with a 1.5m output cable terminated with a 2.1mm x 5.5mm x 10.0mm barrel plug with positive center polarity. Input blades are sold separately, allowing use with different regional plug types.
