Qualities of medium voltage variable frequency drive£¨VFD£©
،ٌ Voltage resource VFD, direct input of 3, 3.3, 4.16, 6, 6.6 and 10 kV, direct output of 3, 4.16, 6, 6.6 and 10 kV, no output transformer necessary. High input power factor, low harmonic current, no power factor corrective capacities and harmonic filters required
،ٌ Sinusoidal multi-level PWM output waveform, no output filter required, can be directly connected to standard induction motor, no harm to the insulation of the cable or the motor, low harmonics of the motor, reduction of vibration of the shafts or the vanes, allowing the maximal length of the output cable of 1000m.
،ٌ Friendly human-machine interface.
،ٌ Modular design of the power circuits simplifies maintenance routine.
،ٌ The medium voltage circuits are linked with the controller by the optical fibers, which keep the controller safe and away from the disturbance.
،ٌ The complete fault monitor circuit, accurate fault alarm and protection
،ٌ Integrated Cooling blower
،ٌ The control logic can be conveniently changed with the help of the integrated PLC
،ٌ Offer both local control and remote control in monitor station, providing convenient controlling options.
،ٌ Support most of the industrial standard protocols (Profibus, Modbus, TCP/ IP etc.)
،ٌ Compatible with industrial standard signal of 0،«10V/4،«20mA
،ٌ Able to operate at either open loop control or closed loop control status with the integrated PID regulator
،ٌ Complete system parameter setup function of VFD
،ٌ Easy installation
،ٌ Excellent performance/price ratio
