Adjustable Low Voltage Frequency Inverter

 Nuclear control module based on DSP, achieve high speed and high performance control. There are three control modes: Vector control & PG control , V/F control, V/F control and PG control. 3 space voltage vector fluctuation form produce methods and dead compensate function to realize large output and low frequency torque control.

    Automatic slip compensation various frequency setting modes and analog terminal can accept the signal of DC to AC. There are internal PID function, high performance closed loop control and PID regulate DC braking function. 

SD90 Series adjustable low voltage frequency inverter provide a wide range of features and application specific parameters. Our inverter are ideal for high performance applications. This type of inverter is designed for advanced application flexibility and control system integration.
