Parts List: 1 x AC Motor Speed Controller Highlight description: [3 Variable Speed Adjustment] This AC motor speed controller has a variable speed function, there are 3 buttons representing three modes: II-Variable, O-Off, I-Full Speed; Adjust the speed to easily adjust the inline and ducted fans, you can freely adjust the speed from 65% to 100% according to the actual demand [Black Clip] The motor speed regulator features a back clip that allows you to easily attach it to your belt while working. The knob provides precise voltage control, while the LED voltage display ensures easy monitoring [Safe to Use] When the current exceeds 15A, the switch automatically cuts off the power supply to ensure the safety of the equipment and the user. The flame retardant housing provides an extra layer of protection. [Compatibility] The unit has a standard receptacle on the bottom that is compatible with Type a and Type B plugs commonly used in the United States. [Wide Application] Ideal for powering fans, small motors, soldering irons and other inductive load devices. It can also be used with resistive loads such as kettles and electric heaters (Note: Built-in circuit boards and electronic components products can not be used, such as induction cookers, energy-saving lamps, brushless synchronous motors.)
