4000W SCR Digital Voltage Regulator Speed Control Dimmer Thermostat,

OUTPUT VOLTAGE ADJUSTMENT---The speed control dimmer thermostat can easily adjust the output voltage on a scale of 0-100% (nonlinear) to power electric device OUTPUT VOLTAGE ADJUSTMENT---The speed control dimmer thermostat can easily adjust the output voltage on a scale of 0-100% (nonlinear) to power electric device 2-WAY LARGE POWER---This speed control dimmer thermostat 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 LARGE AND THICK HEAT---Designed with large and thick heat sink that would enhance heat dissipation, the voltage regulator is adjusted with button which is much more stable than potentiometer & PRACTICAL---Voltage regulator has voltage absorbing circuit and effective protects large power silicon controlled rectifier, longer service life and more WIDE APPLICATION---The speed control dimmer thermostat can be used as power supply for large electrical devices, enough for household appliances or for small factory, 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
