Hi-Link HLK-PM01 220V to 5V 3W AC-DC Power Supply Module
VAT inclusive; Computed calculations added locally.
Overview
The Hi-Link HLK-PM01 provides a convenient way to integrate an isolated low-voltage DC power supply into PCB-based electronic projects. It accepts a wide 90–264V AC input range, making it suitable for common 110V and 220V AC mains environments.
The module provides a nominal 5V DC output and is designed for low-power embedded electronics. Its compact PCB-mount construction makes it useful when a traditional external AC adapter would be inconvenient or too large.
Built-in over-current and short-circuit protection helps protect the power supply and connected circuitry during abnormal operating conditions. The isolated design separates the low-voltage output side from the AC input side, making appropriate PCB layout and enclosure design especially important for safe mains-powered applications.
With output ripple and noise specified at ≤70mVp-p and efficiency of up to approximately 70%, the HLK-PM01 is well suited to applications such as IoT controllers, smart-home devices, Wi-Fi modules, industrial control boards, and DIY embedded systems.

Product Technical Information
Technical Details
The Hi-Link HLK-PM01 220V to 5V AC-DC power supply module is designed for applications where a compact low-voltage power supply needs to be built directly into an electronic system. It converts AC mains power to a regulated 5V DC output for suitable low-power circuits.
Features
- Converts 90–264V AC input to 5V DC output.
- Rated input range of 100–240V AC.
- Up to approximately 70% conversion efficiency.
- Isolated AC-DC power supply design.
- 5V regulated DC output.
- Long-term output current specified at up to 1000mA.
- Short-term maximum output current specified at ≥1200mA.
- Over-current protection.
- Short-circuit protection.
- Low output ripple and noise, specified at ≤70mVp-p.
- Compact PCB-mount construction.
- Suitable for embedded electronics and continuous low-power operation.
Applications
- IoT and smart-home devices.
- ESP8266 and ESP32 projects.
- Arduino-based controllers.
- Smart switches and Wi-Fi controllers.
- Industrial control boards.
- Embedded PCB projects.
- Low-power automation systems.
- DIY electronic devices.
- Mains-powered sensor and control circuits.
How to Use
- Identify the AC input and 5V DC output terminals on the module.
- Connect the AC mains input only after confirming the correct terminals and wiring.
- Connect the 5V output to a compatible low-voltage circuit.
- Verify the output polarity and voltage before connecting sensitive electronics.
- Use an appropriate insulated enclosure and PCB design for the complete assembly.
- Ensure adequate clearance, insulation, and protection from accidental contact with the mains section.
Important Notes
- This module works directly with hazardous AC mains voltage. Installation and wiring should only be performed by a suitably qualified person.
- Never touch the module while it is connected to AC mains.
- The low-voltage output should still be properly insulated and routed from the AC input section.
- Do not exceed the specified input voltage range.
- The 5V output is intended for suitable low-power electronics; verify the actual load requirement before use.
- The stated 1000mA long-term output capability depends on operating conditions, temperature, ventilation, and the specific module.
- Short-circuit and over-current protection do not eliminate the need for proper fuse, enclosure, PCB creepage, and safety design.
- Do not use this module as an exposed power supply.
- Allow approximately 3% measuring deviation where applicable.
Package Includes
- 1 × Hi-Link HLK-PM01 AC-DC 220V to 5V Power Supply Module
