Features: This automatic voltage regulator is used to control the output of 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 2-3KW gasoline generators. Plastic housing is lightweight and provides a better moisture and vibration resistance. Specifications: Housing Material: Plastic Frequency: 50~60Hz Rated Power: 2.5kW Rated Voltage: 220V Phase: 3-phase Used for: 2-3KW 168F gasoline generator Output Voltage: 380V Quantity: 10pcs Weight: 1411g(approx.)
