The Phihong USA PSM04A-050(STD) is a compact 4-watt AC/DC wall mount adapter designed for various applications including wireless communications, portable equipment, peripherals, and PDAs. It provides a stable 5V DC output at up to 750mA current, with a maximum power rating of 3.8W.
This adapter features a wide AC input voltage range of 90 to 264VAC and operates with an efficiency of at least 50%, meeting Level IV standards. Key electrical specifications include low ripple and noise (55mV max), line and load regulation of ±5%, and protection against over-voltage and short circuits. The input connector is a NEMA 1-15P fixed blade, and the output connector is a standard 2.1mm x 5.5mm center positive barrel plug.
Designed for convenience, it has a flip-plug mechanism and measures 69.4mm in length, 48mm in width, and 25mm in height, weighing 145g. The operating temperature range is from 0°C to 45°C. Compliance includes cULus safety approvals and CEC Level IV.
This adapter is suitable for ITE (Commercial) applications and North American region utilization. It also features a no-load power consumption of less than 0.5W and a maximum leakage current of 250uA.
The AC input voltage range is 90 to 264 VAC, with a nominal rating of 100 to 240 VAC.
The adapter is a wall mount (Class II) design, packaged in a box.
