This PWM knob monochromator is a controller that allows for stepless dimming. Power supply voltage: DC 12-24 V Maximum load current: 8A. Widely used to adjust the brightness of LED light strips, such as LED light strips, LED modules, LED strings, etc. Instructions: The knob monochromator is a type of controller that can achieve stepless dimming. With a rotary knob, it's a dimmer that can achieve 0-100% pole-free dimming. Users can adjust the light to a suitable brightness according to actual needs. Used to control all types of LED lighting, such as LED strips, LED modules, LED strings, etc. Instructions for use: 1. First connect the load wire, and then connect the power cord; Before commissioning, make sure there is no short circuit between the cables. 2. Rotate the knob, the functions are as follows: When the knob is turned to the right, the brightness gradually increases, and when it is turned all the way to the right, the brightness is at its maximum. When the knob is turned to the left, the light gradually dims. When turned all the way to the left, the light turns off. Specification: Product name: PWM dimmer switch. Maximum load current: ＜8A.
