Hi-Link HLK-PM01 5V 1A AC-DC Power Supply Module

Product Description

The Hi-Link HLK-PM01 5V 1A AC-DC Power Supply Module is a compact, isolated switching power supply designed to convert high-voltage AC mains into a regulated 5V DC output. With a rated output of 5W and a maximum current of 1A, it provides a convenient power solution for embedded electronics, smart-home devices, microcontroller circuits, and PCB-based electronic products.

The HLK-PM01 accepts an AC input from 100V to 240V, making it suitable for use with common mains power systems. Its integrated AC-to-DC conversion circuitry eliminates the need to design a separate transformer and voltage regulation stage, helping simplify power supply integration into electronic projects and production circuits.

The module provides a regulated 5V DC output, making it suitable for powering compatible microcontrollers, sensors, communication modules, relay circuits, and other low-voltage electronic components. Its compact design allows it to be mounted directly onto a PCB, making it particularly useful for applications where installation space is limited.

An important characteristic of the HLK-PM01 is its isolated power conversion design, which provides electrical separation between the AC input and DC output under the manufacturer's specified conditions. This makes it suitable for properly designed low-voltage power supply circuits, provided that the PCB layout, insulation distances, enclosure, and wiring meet the required electrical safety standards.

The HLK-PM01 is commonly used in smart-home products, IoT devices, industrial control boards, automation circuits, and embedded systems that require a permanent 5V power source directly from an AC mains supply.

Its integrated construction reduces the number of external power supply components required, helping engineers and product developers create compact and practical electronic designs.

Important: The HLK-PM01 operates directly from potentially lethal AC mains voltage. Installation, PCB design, insulation, and testing must be handled with appropriate electrical safety precautions. The module should be enclosed and must never be handled while connected to the mains supply.
