Description
The Hi-Link HLK-PM01 is a PCB-mounted, plastic-enclosed isolated switching step-down power supply module. It converts AC mains directly into a regulated 5V DC output rated at 3W, making it ideal for small projects that need a 5V supply from mains without a bulky external adapter or transformer.
Because it is a switching supply with a wide 100–240V AC input range, output stays stable across grid fluctuations. The isolated design and enclosed plastic housing make it suitable for permanent installation inside smart home devices, automation controllers, and IoT products.
