描述

GECA20-5G is a 20 W commercial-grade AC-to-DC power supply designed for wide-range input applications. It accepts AC input from 90–264 VAC at 47–63 Hz single phase and delivers a regulated 5.1 V output at 4.0 A continuous (25 W peak for 60 s), with line regulation of ±0.5% and load regulation of ±3%. The unit features built-in overvoltage protection (OVP set point 7.0±1.0 V), short-circuit protection with cycling-type power limiting, and comprehensive EMI filtering to meet EN55022 Class B and EN61000 standards. Operating temperature range is 0–45°C with 2.5% derating per °C above 45°C, and the supply achieves 72–80% efficiency with a switching frequency of 70 kHz ±10 kHz. This power supply is ideal for industrial control systems, telecommunications equipment, and embedded applications requiring reliable, regulated low-voltage power in harsh electrical environments.
