Original HI-Link HLK-20M12 AC-DC Step Down Power Supply Module, 85-265V AC Input Convert to 12V DC 20W 1.66A Isolated Switching Converter Board for Smart Home IoT Industrial Control Electronic DIY Pro

This is the authentic HI-Link HLK-20M12 isolated AC-DC switching power supply module, professionally designed for compact embedded power conversion. It supports universal alternating current input ranging from 85V to 265V (covers 110V/220V household grid worldwide), and steadily outputs 12V direct current with maximum 20W power and 1.66A continuous current.

Adopting mature isolated power topology, the module reaches over 84% energy conversion efficiency, features ultra-low no-load power consumption below 0.1W, low output ripple and electromagnetic interference, effectively avoiding signal disturbance to precision circuits. The 3000VAC reinforced isolation between input and output greatly enhances electrical safety, complying with CE, RoHS and EMC safety certification standards.

Multiple intelligent protection circuits are integrated on the interior board, including overcurrent protection, short-circuit protection and overload protection. The module will automatically cut off output under abnormal conditions and resume normal operation after fault elimination, preventing device burnout and extending service lifespan.

With mini enclosed housing and standard through-hole pin layout, it is convenient for direct welding on PCB circuit boards. Widely applicable to smart home devices, IoT sensors, industrial control modules, surveillance cameras, LED lighting, embedded development boards, electronic test instruments and various small DIY power transformation projects.
