10PCS HLK-20M12 AC-DC Power Supply Module, 220V AC to 12V DC 20W Step Down Intelligent Switching Power Module for Household Equipment

HLK-20M12 is an integrated isolated AC-DC step-down switching power module specially designed for household low-voltage equipment. It directly inputs 220V household mains and outputs steady 12V DC with total 20W power to meet the power demand of various small electronic devices.

Adopting mature intelligent switching power topology, the module achieves high energy conversion efficiency, effectively reducing heat buildup during long continuous operation. Multiple safety protection circuits are embedded inside to automatically cut off output under abnormal conditions, preventing damage to the power module and connected loads.

The small-size integrated PCB structure saves installation space inside equipment shells, with reserved solder terminals for convenient wiring. This 10-piece batch pack is ideal for mass production of smart home modules, low-power monitoring equipment, LED small lamps and DIY electronic projects. Stable voltage output avoids device failure caused by mains voltage fluctuation, a cost-effective bulk power supply solution for technicians and manufacturers.
