Fremont, CA (January 19, 2024) — Phihong, a renowned supplier of reliable and cost-effective power conversion solutions, has announced the release of its new high efficiency AA120U series AC/DC desktop adapters rated up to 120 watts.

Housed in a splash-proof case measuring 5.9 x 2.56 x 1.38 inches, the AA120U series features an IEC 320 C14 inlet and meets mandatory U.S. DoE Level VI and EU Ecodesign 2019/1782 efficiency requirements, as well as the more stringent but voluntary European Code of Conduct Version 5 Tier 2 efficiency requirements. Additionally, as of the published date of this press release, the 24V, 48V and 54V output models comply with currently proposed US DoE Level VII requirements while a modified compliant (to Level VII) 12V model may be special ordered.

Ideal for telecommunications, consumer and industrial equipment applications and available in single DC output voltages of 12V, 24V, 48V and 54V, the AA120U series is Class I approved and operates up to +40 degrees C without derating. All AA120U models meets FCC, CAN ICES-003 and EN55032 Class B emissions limits, come standard with short circuit, over-current, over-voltage, and over-temperature protection features, bear UL, CE and UKCA compliance approvals to standard 62368-1 Edition 3, and are approved to 5,000 meters operating altitude.
