AC Motor Speed Controller 50 220V 2000W Adjustable Voltage Regulator Module for Light Dimmer, Temperature

EASY WIRING-- Just simply connect input terminals to either 220V wire(live wire or neutral wire) and output to load, then rotate knob to control voltage. SAFE TO USE-- This Speed Controller has new two-way large power silicon controlled rectifier and the current can be up to 25A, which is a good solution to over current of electric stove wire caused by low resistance during cooling. WIDE APPLICATION-- Voltage Regulator can 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. GOOD PERFORMANCE-- This voltage regulator has voltage absorption circuit which can effectively protect large power silicon controlled rectifier and ensures a longer service life and durability. WIDE ADJUSTABLE RANGE-- With a wide voltage regulating range, the output voltage can be easily adjusted from 50V to 220V.
