HLK-PM03 from Hi Link is a isolated power supply module with input range of 100 volt to 240 volt AC and output of DC 3.3 volt and power rating of 3 watt. Its ultra compact size makes it perfect to use in places where size is a constraint. It is a compact PCB mountable plastic enclosed power supply module. HLK-PM03 Power Supply Module replaces lots of parts from the traditional power supply like diodes, voltage regulator, transformer.
