High Performance AC Variable Frequency Drive 3AC 380V~460V 315KW 355KW 400KW

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.
Small size, high precision, easy operation, high reliability, multi-layer protection of equipment, better than any previous speed regulation mode.
