KD5800-ST Series 220v Input, 380v Output Special Inverter
✍KD5800-ST series single-phase 220V input three-phase 380V output Special Inverter is suitable for the occasions where there is no three-phase 380V electricity, without changing the motor connection, by driving the three-phase 380V asynchronous motor directly from the civil 220V electricity.
✍This series of inverter not only has strong carrying capacity, but also can play the function of soft start and adjust the speed of three-phase asynchronous motor.
✍Note: When selecting the model, the POWER of the inverter should be doubled than the motor. Please consult customer service for details.
