Features The product can easily adjust the output voltage, between 0 and 220 volts, for the use of electrical equipment with different voltage requirements,high strength, high cost performance. 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). The product adopts aluminum casing, which has good heat dissipation effect and can effectively extend the service life of the product. Thyristor is mainly used for resistive load (electric filament incandescent lamp, etc.). Most single-phase AC motors are also available (but not guaranteed). The product is suitable for controlling different electrical equipment, such as electric lamps, fans, motors, etc,very popular. Specification: Max power: 5000W (Resistive instantaneous load ultimate power.) Adjust the voltage: AC 0-220V (from high to low can go to 0, from low to high is about 20V) Efficiency: 90% or more Working voltage: AC 220V Dimensions: Length 85*Width 70* Height 40mm, without protruding knobs and connectors Package list: 1 * Controller Note: Load must be connected to regulate voltage. The actual product color may deviate from the photo due to light. There may be a slight deviation in the measurement of product. Package List
