Overview
Power your low-voltage electronics directly from AC mains with the Hi-Link HLK-PM01 220V to 5V 3W Power Supply Module. This compact, PCB-mountable AC-DC power module provides an isolated 5V DC output from a wide AC input range.
The HLK-PM01 is designed for applications where a compact and reliable mains-to-DC power supply is required. Its enclosed module construction, input-output isolation, and built-in protection features make it suitable for compatible embedded and automation applications.
With a rated output of 5V DC and approximately 3W of output power, the module is commonly used to power microcontrollers, sensors, IoT devices, smart switches, automation controllers, and other low-power electronic circuits. The manufacturer specifies a wide AC input range and built-in over-current and short-circuit protection.
The Hi-Link HLK-PM01 from KathalTech is an excellent choice for compact AC-powered electronics projects requiring a regulated 5V supply.
Warning: This module operates with potentially lethal mains voltage. Installation and handling should only be performed by qualified persons using proper insulation, enclosure, fuse protection, and electrical safety practices.

Product Description
The Hi-Link HLK-PM01 220V to 5V 3W Power Supply Module is a miniature isolated AC-DC switching power supply designed to convert high-voltage AC mains into a regulated 5V DC output.
Its compact size makes it suitable for mounting directly on a PCB, eliminating the need to design a separate mains power supply circuit for many low-power applications.
The HLK-PM01 is commonly used in devices that need a small 5V DC supply while operating from AC mains. Typical applications include smart switches, home automation systems, IoT devices, Wi-Fi controllers, embedded systems, and industrial control circuits.
The module provides electrical isolation between the AC input and DC output, with the manufacturer listing an isolation voltage of up to 3000VAC.

Always verify the pin markings printed on the actual module before wiring.
Why Choose the HLK-PM01?
The HLK-PM01 provides a convenient alternative to building an AC-to-DC power supply from individual components. Its compact design can simplify PCB development for compatible low-power mains-operated devices.
Instead of using a bulky transformer, bridge rectifier, regulator, and additional filtering circuitry, a compatible application can use this compact isolated power module to obtain a 5V DC supply.
Important Safety Notes
DANGER – MAINS VOLTAGE
- The input terminals connect to potentially lethal AC mains voltage.
- Never touch the module while it is powered.
- Always disconnect mains power before wiring or modifying the circuit.
- Use a properly insulated enclosure.
- Maintain safe PCB clearance between high-voltage and low-voltage sections.
- Use appropriate external fuse and protection components where required.
- Keep the module away from moisture.
- Ensure adequate ventilation.
- Only qualified persons should work with mains-powered circuits.
