HLK 2M03 Hi-Link 3.3V 2W AC to DC Power Supply Module

HLK 2M03 Hi-Link 3.3V 2W AC to DC Power Supply Module 

The HLK-2M03 Hi-Link 3.3V 2W AC to DC Power Supply Module is a compact, isolated switch-mode power supply that converts standard AC mains (100–240?V) into a stable 3.3?V DC output at up to 2 W (?600?mA). Its small PCB-mount design eliminates the need for bulky transformers or adapters, making it ideal for embedded systems and space-constrained electronics. The module is efficient, reliable, and provides low-noise output suitable for sensitive circuits.
