1. What Is a Soft Starter for AC?
A soft starter for AC is a device designed to control the startup of alternating current (AC) motors, avoiding the sudden jolts caused by direct power application. SHUYI’s version regulates voltage and current gradually, protecting motors from damage and ensuring stable operation in various settings. It works with a wide range of AC motor sizes, from small fans to large industrial pumps..
