AC 220V 4000W SCR Electric Voltage Regulator Dimmer Temperature Motor Speed Controller with Fan

Description: This is a easy-to use voltage regulator for controlling light brightness, speed or temperature. The big power voltage regulator is equipped with two-way silicon controlled rectifier, which is very convenient and practical. The voltage regulator has a large power and can be used for large household or small industrial electrical appliances of which power is less than 4000W(for resistive loads only, power should be reduced for inductive or capacitive loads). Features: ? This item has two-way large power silicon controlled rectifier and the current can be up to 20A, which is a good solution to over current of electric stove wire caused by low resistance during cooling ? Convenient to use, simply connect input terminals to either live wire or neutral wire(110V to 220V) and output to load, then rotate knob to control voltage ? With a wide voltage regulating range, the output voltage can be easily adjusted from 0V to 220V ? Could be widely used as heat controller on electric stoves, water heaters, light dimmer on lamps, speed controller on small motors, or temperature controller on electric soldering iron, etc ? The resistive load power should be less than 4000W, and power should be largely reduced(half or more) for inductive or capacitive loads, otherwise controller and load will burn out Specifications: Input Voltage: AC110V to 220V Max Power: 4000W(resistive load) Output Voltage: Variable from 0V to 220V AC Size: 85 x 60 x 45mm / 3.34 x 2.36 x 1.77" Package Includes: 1 x Voltage Regulator
