Grahikum PWM_AC 50-220V 2000W(max) 25A SCR Constant Voltage AC Motor Speed Controller LED Dimmers Motor Control Electronic Hobby Kit

This controller uses high-quality scr. And the max current is up to 25a. For the safety, we suggest the continuous load current is within 5a. This ac voltage regulator can be used to control ac motor speed, ac light and heating wire temperature. Inductive or capacitive load power should be reduced. For Example, recommended for motors within 1000w operating instruction : Before you attempting to wire the controller, make sure all power is disconnected. 1. Cut any one of the battle line or zero line of the lamp or electrical appliances, and connect wires refer to the "wiring diagram" (No.6 picture) 2. Turn on the power, and adjust the potentiometer. 3.If the adjustment range is found to be small, please adjust the blue potentiometer on the product counterclockwise to set the maximum adjustment range to 50v to input voltage.
