Dimmer 3000 watt, Hilitand 4000W High Power SCR Electronic Voltage Regulator, AC 220V Motor Speed Controllers, Control Thermostat

VOLTAGE: This Item has new two-way large power silicon controlled rectifier and the current can be up to 40A, which is a good solution to over-current of electric stove wire caused by low resistance during cooling. HIGH QUALITY: Designed with large and thick heat sink that would enhance heat dissipation. Voltage regulator has voltage absorbing circuit and effective protects large power silicon controlled rectifier, longer service life and more APPLICATION: 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. EASY TO USE: It can easily adjust the output voltage on a scale of 0-100% (nonlinear) to power electric device. This voltage regulator is adjusted with button which is much more stable than potentiometer. It can be used as power supply for large electrical devices, enough for household appliances or for small factory.
