2W/3W/5W/10W/20W HLK-xxM05 Series AC-DC

Hi-Link AC to DC Power Supply Modules are compact, high-efficiency, and fully isolated switching power converters designed for embedded electronics, IoT devices, smart home systems, and industrial automation projects. Each module converts 100–240V AC mains voltage into a stable, regulated DC output—making it the safest and most reliable way to directly power low-voltage electronic circuits from the grid.

All Hi-Link modules are built to meet UL, CE, and EMC safety standards, offering exceptional protection features such as short-circuit protection, overload protection, high isolation, and low ripple noise. Their PCB-mountable, fully enclosed design ensures long-term stability, high power density, and minimal heat generation.

Engineered with global input compatibility, low power consumption, and high reliability, Hi-Link modules have become the industry standard for powering smart home devices, automation controllers, communication equipment, sensors, and microcontroller boards, including ESP8266, ESP32, and Arduino.

Whether your project requires 2W, 3W, 5W, 10W, or 20W output, Hi-Link offers the perfect module with proven stability, compact size, and international safety approval.
