Description: _x000D_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 2000W(power should be reduced for inductance or capacitance loads). _x000D__x000D__x000D_Features: _x000D_This item 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. _x000D_Convenient to use, simply connect input terminals to either 220V wire(live wire or neutral wire) and output to load, then rotate knob to control voltage._x000D__x000D_With a wide voltage regulating range, the output voltage can be easily adjusted from 50V to 220V. _x000D_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. _x000D_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._x000D__x000D__x000D__x000D_Specifications: _x000D_Input Voltage: AC220V(NOT 110V)_x000D_Max Power: 2000W _x000D_Output Voltage: AC 50V to 220V_x000D_Size: 48 x 35 x 28mm / 1.89 x 1.37 x 1.1" _x000D__x000D__x000D_Package Includes: _x000D_1 x Voltage Regulator _x000D__x000D__x000D_Note: The input voltage of this voltage regulator can NOT be 110V. 1This item 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 2Convenient to use, simply connect input terminals to either 220V wire(live wire or neutral wire) and output to load, then rotate knob to control voltage 3With a wide voltage regulating range, the output voltage can be easily adjusted from 50V to 220V 4Could 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 5This voltage regulator has wave voltage absorption circuit which can effectively protect large power silicon controlled rectifier and ensures a longer service life and durability
