AA120U Series Description: The Phihong AA120U Series delivers reliable 120W AC-DC desktop power adapters designed for industrial, test and measurement, networking, and peripheral applications. Featuring a non-vented enclosure with a standard IEC 60320 C14 input, these adapters provide a rugged and compact solution that integrates easily into demanding systems. Built for high efficiency, the AA120U complies with DOE Level VI, EU ErP Lot 7 (2019/1782), and EU CoC Tier 2 energy standards. With an average efficiency of 88–89%, even under light loads, and no-load power consumption below 0.15W, this series supports reduced operating costs and energy-conscious performance. The AA120U is available in output voltages from 12V to 54V, offering up to 120W of continuous power with ample current capacity to meet diverse application requirements. Protection features include over-voltage (latch mode), over-current auto-recovery, and short-circuit auto-recovery, ensuring safe and stable operation. Designed for reliability, the adapters operate from 0°C to +60°C without derating and support altitudes up to 5,000 meters. Compliance with cULus / IEC/EN 62368-1 safety standards, Class B EMI performance, and immunity to ESD, surge, and flicker disturbances makes them well-suited for sensitive electronic equipment. Compact in size at 150 × 65 × 35 mm, the AA120U series includes DC cables from 1 to 1.5 meters, with options such as a 4-pin mini-DIN or a right-angle barrel connector, depending on the voltage model. Combining efficiency, safety, and global approvals, the AA120U Series is a dependable external power supply for high-performance systems.
