HLK-PM12 from Hi-Link is a isolated power supply module with input range of 100 volt to 240 volt AC and output of DC 12 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-PM12 Power Supply Module replaces lots of parts from the traditional power supply like diodes, voltage regulator and transformer.

There are many advantage of these modules, such as :Global input voltage range, low temperature rise, low power, high efficiency, High reliability, high security isolation, etc.

It has been widely used in smart home, automation and control, communications equipment, instrumentation and other industries, when applied to electromagnetic compatibility relatively harsh environment, reference should be circuit.
