Product Description
The HLK-PM01 5V 3W Power Supply Module is a compact and reliable AC to DC converter designed for embedded electronics and industrial-grade applications. It efficiently converts 100V–240V AC input into a stable 5V DC output, making it ideal for powering microcontrollers and low-power circuits.
Built with an isolated switching design, this module ensures high safety and protection when working directly with AC mains. It includes internal protection against overload and short circuits, helping safeguard connected components.
Its small form factor makes it easy to integrate directly into PCB designs, especially in space-constrained applications like smart home devices and IoT systems. This eliminates the need for bulky transformers or external SMPS circuits.
The module is widely used in automation systems, smart switches, wireless modules, and DIY electronics projects. It provides a consistent and regulated output, which is essential for stable performance of digital circuits.
With high isolation voltage and long operational life, the HLK-PM01 is a dependable solution for both prototyping and production-level designs.
