General

High Voltage Variable Frequency Drives are designed to be highly reliable with high-performance, yet easy to use.It can satisfy users' need for changing the speed of fans or pumps,as well as improve the productivity.

The series are compatible with all types of three-phase medium voltage asynchronous motors.

Specification and advantages :
1. Voltage resource VFD, direct input of 3,3.3,4.16,6,606 and 10 kV,direct output of3,4.16, 6,6.6 and10 kV,no output transformer necessary. High input power factor, low harmonic current, no power factor corrective capacities and harmonic filters required.
2. 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,with the maximal length of the output cable of 1000m.

3. Friendly human-machine interface.
4. Modular design of the power circuits simplifies maintenance routine.

5.The medium voltage circuits are linked with the controller by the optical fibers,which keep the controller safe and away from the disturbance.

6. The complete fault monitor circuit, accurate fault alarm and protection.

7. Integrated cooling blower

8. The control logic can be conveniently changed with the help of the integrated PLC.

9. Offer both field control and remote control in monitor station, providing convenient controlling options.

10. Support most of the industrial standard protocols (Profibus, Modbus, TCP/IP, etc.)

11. Compatible with industrial standard signal of 0-10V/4-20mA

12. Able to operate at either open loop control or closed loop control status with the integrated PID regulator.

Spare Parts of MV VFD Storage and Replacing

Spare parts is one of important parts of Medium Voltage Variable Frequency Drive (MV VFD). After receiving the spare parts, please inspect it for damage immediately. If find any damage, please make report immediately. To ensure the spare part not to be damaged, please pay attention to the following content: The store location should without any impacting or vibration and also should prevent the damage caused by humidity, frost, temperature, grit. The spare parts shall be stored in dry ambient, which is far away from the corrosive gas. All printed circuit board should be stored in electrostatics proof package. Please handle the packaged spared parts carefully for the convenient of troubleshooting and maintenance after send back to factory.

 Replacing Spare Parts from the original package, prevent carefully from electrostatics discharging. The impropriety operation may cause sensitive parts damage, and the following procedures should be followed .Even short-distance transportation, spare part should also be shipped in electrostatics proof package

When handling the PCB, always hold it by its edge to prevent terminals and component damage. The PCB audits component should place on a grounded operation table to prevent electrostatics effect .The failed PCB should also be shipped or delivered in electrostatics proof package to prevent the electrostatic damage.
