GOOD PERFORMANCE-- This voltage regulator has wave 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.

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.

So as to achieve the effects of dimming, temperature, voltage and speed.

Before you attempting to wire the controller, make sure all power is disconnected.
