Features: _x000D_ This automatic voltage regulator is used to control the output of gasoline electric generator. _x000D_ It is connected to the generator with several wires to stabilize the voltage. _x000D_ By increasing or decreasing the generator control voltage, the output voltage of the generator increases or decreases accordingly. _x000D_ The voltage regulator is suitable for 6.5KW 7KW 8.5KW 2-phase 6-wire generators. _x000D_ It has a ABS housing which can offer a good protection. _x000D_ _x000D_ _x000D_ Specifications: _x000D_ Material: ABS_x000D_ Used for: 6.5kW~8.5kW gasoline generator (450V 680VF) _x000D_ Start Method: Electrical starting _x000D_ _x000D_ _x000D_ Note:_x000D_ 1) A higher output AVR definitely works perfect on a generator of low power output while on the contrary, a low power output AVR CAN NOT be used for a generator of higher power output._x000D_ 2) Most of replacement AVRs in the market are rated only 5KW and can only handle a maximum power of 6KW. They are too weak to be used unless the total load of your generator won't exceed 5KW._x000D_ 3) If our AVR is out of adjustment for your generator, please MANUALLY turn clockwise or counter-clockwise a small bronze screw in a blue rubber part to reach your desirable power output. Clockwise turning is for increasing and counter-clockwise turning for decreasing voltage output._x000D_ 4) There may be a capacitor voltage regulator installed in your generator. If so, you shall find a compatible generator capacitor. _x000D_ _x000D_ _x000D_ Package Includes: _x000D_ 1 x AVR _x000D_ _x000D_ _x000D_ Note: Please allow 1-2mm error due to manual measurement. Thanks for your understanding.
