Mean Well GS25A05-P1J is an AC/DC desktop adapter that delivers a regulated 5V output at 4A, providing up to 20W of power. It accepts a universal AC input from 90 to 264 VAC at 47 to 63 Hz, making it suitable for global use. The adapter achieves a typical efficiency of 84.5% at 230VAC and maintains a low no-load power consumption of 300mW max.
This model features tight output regulation with line regulation of ±1% and load regulation of ±5%. Ripple and noise are limited to 50mVp-p maximum. Protection circuits include overload protection (110-150% of rated output) and overvoltage protection (105-135% of rated output). The adapter has a hold-up time of 50ms at 230VAC and 15ms at 115VAC.
The desktop package measures 93.0mm x 54.0mm x 36.0mm and weighs 230g. Termination is via a barrel plug with 2.1mm inner diameter and 5.5mm outer diameter. The adapter operates in temperatures from 0°C to 50°C and can be stored from -20°C to 85°C. It is designed to meet EN55032 Class B conducted and radiated emissions and EN61000-4-2,3,4,5,6,8,11 immunity standards (Class A).
