Product Overview
The HLK-5M05 AC-DC Power Supply Module is a compact and fully enclosed switching power supply designed to provide a reliable 5V DC regulated output directly from AC mains voltage. Supporting a universal 100V-240V AC input, it eliminates the need for bulky transformers and external power supplies.
With 5W output power, the module can deliver up to 1A continuous current, making it suitable for powering microcontrollers, wireless modules, sensors, relay boards, displays, and other embedded electronics.
The module features 3000VAC input-to-output isolation, helping improve electrical safety and reduce interference in sensitive electronic applications. Every module undergoes full-load testing to ensure stable performance and long operational life.
