Description
The Hi-Link HLK-2M05 5V/2W AC/DC Switch Power Supply Module is a compact, high-efficiency plastic-enclosed PCB-mounted isolated switching power supply designed to convert standard AC mains input (90–264V AC) into a stable, regulated 5V DC output at 2W total power. Developed by Hi-Link, this ultra-small power module is engineered to withstand grid fluctuations while offering exceptional reliability, low ripple, and minimal no-load power consumption (<0.1W).
Built to meet stringent international UL and CE standards, the HLK-2M05 incorporates comprehensive output overload and short-circuit protections. Its robust thermal and electrical design ensures high power density and safety isolation, making it an ideal drop-in power solution for microcontrollers, smart home sensors, compact automation hardware, and IoT electronics.
