KD5800-ST Series Single Phase 220V to 3-Phase 380V VFD
In general, most AC motors are three-phase 380V and cannot operate without three-phase power.
You can only find a way to convert single phase 220V to three phase 380V. However, many equipment on the market with single-phase 220V input, three-phase 380V output are very expensive, so that many users in need take a step back.
KARDA 1-phase 220V to 3-phase 380V VFD (frequency inverter) is a perfect solution to solve this problem. Running a 3-phase 380V AC motor on a 220V single phase voltage for speed control is easy to be done, especially in some areas where there is no 380V power supply.
KARDA customized VFDs feature with 1hp to 30hp power rating, built-in RS485 communication interface, IP20 for body, V/F control mode.

✍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.
