1.   To converse SPWM voltage current waveform of frequency inverter to approximate sine wave waveform (For the line load feature, the COS is greater than 0. 3 and T H D is less than 5%);

2.   Protect motor insulation system, reduce bearing current, prolong service life, reduce motor noise;

3.   With general asynchronous motor can replace frequency induction motor use;

4.   Effectively restrain the high frequency loss and RF radiation interference, in certain occasions without to use a shielded cable, lowering the field Cable requirements;

5.   Cable between motor and frequency inverter can extend to 500 meters, the longest can reach 3000 meters above;

6.   We have 220 V 380 V 440V 690V 1140V three phase variable frequency drive system;

7.   Suitable motor and inverter power range: 0. 4KW - 1600 KW;

8.   Suitable frequency inverter output carrier frequency range: 1.5-16 KHz;

9.   Basic frequency range: 0 to 400 Hz (above 50Hz order must tell us when order);

10. Driving load forms: asynchronous motor (After special design can use for EPS UPS and the surrounding power supply system);

11. Heat resistant level: F grade (for reactor part);

12. Protection level: IP 20.
