The Hi-Link HLK PM03 3.3V/3W Switch Power Supply Module is a miniature PCB-mount AC/DC switching power supply designed to convert household AC mains voltage (90V to 264V AC) into a clean, isolated, and regulated 3.3V DC output. Built inside a compact, flame-retardant plastic casing, it provides a reliable power solution for space-constrained electronics, smart home automation hubs, and 3.3V microcontroller circuits.
It features advanced green power technology with ultra-low no-load power consumption (< 0.1W), high conversion efficiency, and low ripple and noise. The module includes integrated over-current, short-circuit, and over-temperature protection circuitry that automatically recovers the unit once a fault condition is cleared, ensuring safe continuous operation in industrial and consumer applications.
