K-Drive wholesale 220V 380V ac variable frequency inverter 0.75kw to 630kw vfd drives
Product Details
380V 440V 315KW 355KW 400KW Frequency Inverter VFD For Asynchronous Motor
1. Independent duct design
Independent air duct design, effectively preventing dust entering inverter, causing short-circuit and other faults and improving reliability
Use bigger air volume and long life cooling fan effectively reduces the internal temperature rise of the inverter and ensures reliable and stable operation of inverter.
2. Positioning Capability without External Devices
Use an IPM motor to perform position control – without motor feedback. Electrical saliency in IPM motors makes it possible to detect speed, direction and rotor position without the use of external feedback devices.
Positioning functionality without a PLC. Visual programming in DriveWorcsEZ eliminates the need for external controllers by giving the user the power to create customized functions such as position control.
