15HP ( 11KW ) High Frequency VFD Frequency Converter 3AC 380V~460V

 

The KD330 series inverter is a universal high-performance drive vector control function inverter.
The inverter-controlled speed control system is based on advanced technical control theory and intelligent control means to achieve extremely high responsiveness and stability.
With its unique super performance and superior cost performance, the inverter meets the performance requirements of the spindle with wide speed range, high speed stability, strong overload capability, large low speed torque and short acceleration and deceleration time.
