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.
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.
