Hi-Link HLK-5M05 5V 5W AC to DC Power Supply

Overview

A compact isolated AC-DC power module that converts mains AC voltage directly to a regulated 5V DC output, designed to be embedded directly into a project enclosure.

Key Specs

Features

• No external transformer required
• Isolated output for improved safety
• Higher power rating than the HLK-PM01 (5W vs 3W)

Compatible With

Any 5V-powered project (Arduino, ESP boards, relay circuits)

Use Cases

• Embedded mains-powered IoT devices
• Projects with slightly higher current draw than the smaller HLK-PM01 supports

FAQ

Is it safe to connect to mains voltage? Yes, it's designed for direct AC mains connection, but standard high-voltage safety practices still apply.
