3 hp~15 hp(2.2kW~11kW) Single-Phase 220V to 3-Phase 380V VFD | KD5800-ST

KD5800-ST Series Model Selection Table:

KD5800-ST Series 220V to 380V VFD is used to convert single-phase 220V power into three-phase 380V output for running industrial motors. It is widely used in CNC machines, pumps, compressors, and manufacturing equipment.

Many users search for how to run a 380V motor on 220V power. The most efficient solution is using a Variable Frequency Drive (VFD) that supports voltage boosting and phase conversion.

This 220V to 380V VFD supports single phase 220V input and provides stable three phase 380V output for motor speed control and energy saving.

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.
