Feature: _x000D_ The product can easily adjust the output voltage, between 0 and 220 volts, for the use of electrical equipment with different voltage requirements. _x000D_ Thyristor is mainly used for resistive load (electric filament incandescent lamp, etc.). Most single-phase AC motors are also available (but not guaranteed). _x000D_ The product is suitable for controlling different electrical equipment, such as electric lamps, fans, motors, etc. _x000D_ The ultimate resistance load power of the product is 5000 W. It should be reduced for a long time. It is suggested that the resistance load should be less than 2200W at room temperature (key parameters, please note). _x000D_ The product adopts aluminum casing, which has good heat dissipation effect and can effectively extend the service life of the product._x000D_ _x000D_ _x000D_ Specification:_x000D_ Max power: 5000W (Resistive instantaneous load ultimate power.) _x000D_ Adjust the voltage: AC 0-220V (from high to low can go to 0, from low to high is about 20V)_x000D_ Efficiency: 90% or more _x000D_ Working voltage: AC 220V_x000D_ Dimensions: Length 85*Width 70* Height 40mm, without protruding knobs and connectors_x000D_ _x000D_ Package list:_x000D_ 1 * Controller_x000D_ _x000D_ Note:_x000D_ Load must be connected to regulate voltage._x000D_ The actual product color may deviate from the photo due to light._x000D_ There may be a slight deviation in the measurement of product.
