Input voltage: three phase 220v AC
Output voltage: three phase 0~rated input voltage
Rated power: 0.75kw (1HP)
Rated current: 4.5amp
Description：this kind of frequency converter(speed contoller) is used for asynchronous motor,which is support two wiring methods, start type (Y wiring method) and delta type (∆ wiring method).
The frequency converter support this application scenario, while the motor is three phase 380v voltage ,but the power supply is three phase 220v.
The figure below is a schematic diagram of the motor junction box. The left side is the star connection method. The connecting piece is removed and changed to the shape of the right figure.
Noted: It is suitable for small power motors.
