A2-0.75K-A

* All Chinese setting interface is optional
* Wide voltage input: 3 phases 323-528V
* Quick start up and shut down (A4 series 0.01s quick start up and shut
down)
* Motor speed tracking restart, smooth without impact
* Low frequency high torque: closed loop vector starting torque: closed loop vector starting torque 0.00Hz 180%
It is widely used in ceramic cement, power power plants, glass, packaging, printing,
cable, water treatment and other transmission and fan control

  • Characteristic performance:
    Revolving speed
    tracking start    		The frequency converter recognizes the speed of the rotating motor and directly tracks the start from the identified frequency.
    The current and voltage in the starting process are smooth and no-impact
