When your custom electronics project or IoT device requires a dedicated 5-Volt power rail such as for driving microcontrollers, ESP8266 Wi-Fi modules, or smart home sensors the HI-LINK HLK-PM01 provides a professional, plug-and-play solution. Instead of relying on a bulky external power adapter, this miniature module solders directly onto your custom PCB. It takes standard, fluctuating household or industrial AC mains power and converts it into a highly regulated 5-Volt DC output, providing up to 3 Watts (600 milliamps) of continuous power in an incredibly small footprint.

Renowned for its safety and reliability in commercial applications, the HLK-PM01 is fully encapsulated in a flame-retardant plastic casing and potted with a thermally conductive epoxy. This completely seals the sensitive internal switching circuitry away from dust, moisture, and intense physical vibration. It meets strict global safety and energy efficiency standards, featuring an ultra-low standby power consumption that makes it ideal for smart home devices that remain plugged into the wall 24/7.

Key Features & Functional Advantages

  • Direct AC to DC Conversion: Readily accepts universal AC mains voltages (100V to 240V AC), allowing your device to be plugged directly into the wall anywhere in the world without a step-down transformer.

  • PCB Mountable: Features standard through-hole pins designed to be soldered directly onto your custom circuit board, drastically reducing the physical size of your final product.

  • Fully Encapsulated: The potted interior completely isolates the internal electronics, providing excellent heat dissipation while rendering the module highly resilient in harsh, dusty, or humid environments.

  • Low Standby Power: Highly energy efficient, drawing less than 0.1 Watts when your device is in sleep or standby mode.

  • Comprehensive Protection: Engineered with built-in safeguards against output short circuits and over-current draws, ensuring both the power supply and your downstream circuit remain safe.

Perfect For

  • Smart Home Devices: Providing the necessary 5-Volt power to run Wi-Fi switches, relays, and home automation hubs directly from the mains.

  • IoT Sensor Nodes: The ideal internal power supply for remote monitoring stations and ESP32/Arduino-based sensors.

  • Custom Enclosures: Eliminating the need for external "wall wart" power adapters, allowing you to design clean, self-contained devices with a single AC power cord.

  • Industrial Automation: Delivering isolated, reliable 5-Volt logic power for custom controllers and low-voltage displays.
