    offer closed loop vector control AC drive for Cranes and hoists, Winding, Material handling, Automotive testing, Extruding...
    As a professional manufacturer of frequency inverters (variable speed drives), we offer world class high performance closed loop vector control AC drive (frequency inverter, VSD) (http://www.inverter-china.com/closed-loop-vector-control-AC-... )

    Applications:
    Cranes and hoists, Winding, Material handling, Automotive testing, Extruding, Intelligent Drives...

    Power rating : 0.4 kw ~630.0 kw (less than 1 hp to 840 hp)
    Frequency scope: 0.00 ~ 800.00Hz (for some models, the maximum frequency is 2000 hz)
    Voltage grade: 3 phase 220VAC, 380VAC, 400VAC, 440 VAC, 460V, 480VAC, 575V, 660V, 690 VAC, 1140V.



    First rate closed loop vector control (flux oriented control) variable frequency drive (VFD, frequency inverter, VSD), strictly inspected, tested & controlled quality, strong performance, international stardards certified (CE, ABS, TUV, ISO...)

    This closed loop vector control (field oriented control, flux oriented control, indirect torque control) variable speed drive (AC drive), whose central control module based on DSP, realizes high-speed and high performance control, achieves perfect motor control via servo function, and offers comprehensive drive solution in motion control. It's suitable for large inertia, high accuracy, potential energy load, fast response and other high-end occasion.

    Function of energy-saving control, speed control, slip compensation, torque compensation, torque control, parameter copy and other high-end function.

    4 control modes available: V/F control (scalar control), V/F with PG, seedless sensor vector control (), vector control with PG card.
    Low-frequency large torque, 0.3Hz with the 180% torque output;
    Powerful communication function, RS485/MODBUS standard interfaces.
    Dead zone compensate function and Automatic slip compensate, 180% torque output can come out below 0.5HZ frequency.
    Eight switch inputs, three analog inputs, two analog output, 0-10V or 0-20mA from inside the scope of the definition signal!
    Support feedback signal: 0-10v, 1-5v, 0-20mA, 4-20mA
    Built-in PID self-adjusting
    Rotate speed tracking start and power-off reset function
    High effective function on default record and recheck, easy trouble -shooting.
    Unique EMC design minimizes pollute to electricity resource.
