Features: The controller adopts a strong galvanized iron shell, which is not easy to be deformed or damaged, the internal parts from being damaged. Highly power voltages regulator, stepless regulation, help adjust speed, temperature, voltages and light. Separate switches control, freely control the input power and cut off power. Adopt multifunctional industrial socket, thicken coppers part design, with fine contact and safety. Applicable to excitation motors, electric tool and resistive loads, such as fan, handheld routers, electric kettles, electric stove, electric soldering irons.
