4000 W AC voltage regulator, speed controller for 220 V electric motors, 220 V motor speed controller for brushed motors

REGULAR VOLTAGE RANGE FROM 10V TO 220V – The adjustable voltage range of 10V to 220V is truly smooth, making it ideal for low-voltage household appliances requiring heating wire control.

DUAL CAPACITY CAPACITOR – The voltage regulator uses an ammeter capacitor and a metal film capacitor to absorb voltage spikes and surges. This ensures more efficient and safer operation.

VERSATILE APPLICATION – The voltage regulator is used to control the speed, brightness, voltage, and temperature of various electronic devices such as electric ovens, water heaters, lamps, small motors, etc.

ROBUST PERFORMANCE – The voltage regulator features a high-quality hinged cover made of 1.5mm thick aluminum and stainless steel, ensuring safety and convenience.

EASY OPERATION – The voltage regulator is simple to use. Speed, temperature and other settings can be conveniently adjusted via the rotary knob.
