A6-450K-A

discuss personally

* optional operation interface for all Chinese Settings
* wide voltage input: 3 phase 323-528v
* quick start and stop (A4 series 0.01s quick start and stop)
* motor speed tracking starts again, smooth without impact
* low frequency high torque: the starting torque of the closed loop vector is 0.00hz 180%
Widely used in ceramic cement, power plant, 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
