Usage Tips:AVR Single-phase Automatic Voltage Regulator Rectifier For 7/ 7.5/ 8KW Generator 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. Power: 7KW-8KW Starting mode: Electric start Size: As shown in picture Phase: single phase Type: half moon Wire: 4 wires connector + 2 wires Capacitor: 450v 470uF Application: Fit for gasoline generator Color: Black Material: Plastic size: 14*5*2cm Package Contents: 1x voltage regulator Only the above package content, other products are not included.
