Feature:1. COPPER COIL: The frequency inverter adopts excellent copper core coil with strong resistance and high load capacity, stable and reliable in performance.2. STABLE CONNECTION: Support VF control, vector control and output torsion control, built in RS485 communication interface, stable connection with less interference.3. MULTIPLE CONTROL: With speed potentiometer and external panel, built in synchronous control and proportional synchronous control, has 6 speed control modes.4. GOOD COOLING: Adopt strong cooling fan design, built in aluminum block to assist heat dissipation, the variable frequency drive has good heat dissipation effect.5. APPLICABLE SCENES: The inverter is suitable for fan, pump, automatic machine tool, engraving machine, etc., with small size, large torsion, strong practicability.Specification:Item Type: Frequency InverterMaterial: PC, AluminumModel: SKI780 5D5G 4Applicable Motor: 5.5KW 7.5HPInput: AC3PH 380V±15%, 15A, 47Hz-63HzOutput: AC3PH 0V-380V, 13A, 0Hz-400HzProtection Class: IP20Installation Height: Up to 1000 meters (3280 ft) above sea level, if the installation height is higher than this value, the current should be reduced by 1.2% for every 10 meters (328 feet) of heightOperating Ambient Temperature: 0-40℃ (32-104℉)Storage Temperature: -20-55℃ (-4-131℉)Air Humidity: 5%-85% during operation, no condensation or freezing; 5%-95% during storage.Package List:1 x Frequency Inverter1 x User ManualNote:Pay attention to electricity safety when installing and using.
