According to the design, which is used to manage one or more AC or DC voltage. Prevent generator from suffering damages of voltage fluctuation or over load. It uses an electromechanical mechanism, or passive or active electronic components. Features: Stop fluctuation of voltage, automatically maintaining generator output terminal voltage at a set value. In addition to the shunt regulator, the regulator operates through a number of fixed internal comparison of the actual output voltage of the reference voltage. Any differences are used to control the zoom and regulatory elements. 5-8KW Generator AVR Automatic Voltage Regulator Rectifier Single Phase, Weight: 0.5180863157 Pounds, Manufacturer: Prterver
