electricity is still predominantly powered by alternating current, but computers, LEDs, solar cells and electric vehicles all run on DC power. And methods are now available for converting direct current to higher and lower voltages. This is a HLK-2M05 Hi-link 5V 2W AC to DC Power Supply Module is plastic enclosed PCB mounted isolated switching step-down power supply module. It can supply 5V DC from 120V AC – 230V AC and has a power rating of 2 Watt. This makes it perfect for small projects that need a 5 volt supply from mains.
