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. Byincreasing or decreasing the generator control voltage, the output voltage of the generator increases or decreases accordingly. The voltage regulator is suitable for 2KW-3.5KW single phase generators. It is sealed with resin which provides a better moisture and vibration resistance.
