220v 4000w High-power Scr Voltage Regulator Motor fan electric Drill Speed Controller Governor

Description

The input is alternating current (AC), the output is also alternating current (AC), not direct current (DC) 4000W refers to the power when working under resistive load, and resistive load refers to lamps, heating wires, etc. The inductive load is 1/3 of the resistive load. Electrical appliances with metal casings should be grounded safely. against high temperature, heavy pressure, and eliminates potential safety hazards. Overload protection switch, independent switch control
