Automatic Voltage Regulator AVR for 2 Phase 6 Wire Petrol Generator - 6.5KW 7KW 8.5KW Arc Shaped Features: This automatic voltage regulator is used to control the output of gasoline electric generator. It is connected to the generator with several wires to stabilize the voltage. By increasing or decreasing the generator control voltage, the output voltage of the generator increases or decreases accordingly. The voltage regulator is suitable for 6.5KW 7KW 8.5KW 2-phase 6-wire generators. It has a ABS housing which can offer a good protection. Specifications: Material: ABS Used for: 6.5kW~8.5kW gasoline generator (450V 680VF) Start Method: Electrical starting Note: 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. 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. 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. 4) There may be a capacitor voltage regulator installed in your generator. If so, you shall find a compatible generator capacitor. Package Includes: 1 x AVR Note: Please allow 1-2mm error due to manual measurement. Thanks for your understanding.
