Features: Stop fluctuation of voltage, automatically maintaining generator output terminal voltage at a set value. Prevent generator from suffering damages of voltage fluctuation or over load. It uses an electromechanical mechanism, or passive or active electronic components. According to the design, which is used to manage one or more AC or DC voltage. 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<br><br>Tips: The product may be updated constantly ,Due To Different Batches, The Actual Product May Have Slight Differences Or Color Differences, Which Does Not Affect Use Material: Plastic colour: Black<br><br>Package Contents: 1 x Voltage Regulator Rectifier(Randomly line color, do not accept designated)<br><br>Only the above package content, other products are not included.
