Features: This automatic voltage regulator is used to control the output of electric generator. Used to stop fluctuation of voltage, automatically maintaining generator output terminal voltage at a set value. It is connected to the generator with 6 wires to stabilize the voltage. The voltage regulator is suitable for 5KW 188F gasoline generators. Plastic housing is lightweight and provides a better moisture and vibration resistance. Specifications: Housing Material: Plastic Type: without Metal Plate Used for: 188F gasoline generator Suitable Power: 5KW Phase: 2-phase Wire: 6-wire Optional Type: with small capacitance (250V 470uF), with large capacitance (450V 680uF) Weight: Approx. 218g Package Includes: 1 x Automatic Voltage Regulator Note: Please allow small size error due to manual measurement.
