5 tips for using 1-phase 220V to 3-phase 380V VFD
- The power at the input of the variable frequency drive must be sufficient, otherwise the operation will jump under voltage fault can not be normal operation.
- Single phase 220v to three phase 380v VFD belongs to the boost circuit step-up, for the load side of the maximum for the light-load site below 30hp (22kW), in terms of selection, the light-load motor use a large level of VFD, heavy-load site use a large two-level VFD.
- 1-phase to 3-phase VFD can only be used for motor class inductive load, can not be used as other load power supply.
- The VFD is not suitable for the need to quickly start and stop the site, and the occasion of the bit energy load.
- Part of the equipment motor can be used by changing the motor connection three-phase 220V electricity (such as motor star connection state is three-phase 380V motor, can be changed to delta connection can use three-phase 220V, the specific can consult the motor manufacturer), at this time can buy ATO single-phase 220V to three-phase 220V VFD to solve the problem of phase change.
