Typical application(VFD)
Power plant, water supply, cement, iron&steel, petrochemical, oil&gas Fetures(VFD) 1. High integrated techology and completely digital control system, good anti interference ability 2. Control system power supply redundant design 3. Multi monitor for power units 4. Power unit bypass function 5. Standard RS485terminal to communicate with DCS 6. More than 30 kinds of protection for inverter and motor 7. Full parameters record, tempeartureand DC bus of each power unit can be monitored and indicated 8. High efficiency>98% and power factor>0.96, low harmonic design<2% 9. DSP control system optimize modulated waveform to ensure perfect waveform without harmonics 10. Better energy saving function, self-regulation for voltage when detecting light load to save energy 11. Big voltage, current margin design. Adopt 1700V IGBT, twice voltage margin, twice current margin 12. System and power unit bypass function. Inverter can auto switch between power frequency and variable frequency. Bypass failed power unit, the inverter run continuously derating 13. Speed trace function 14. Wide national grid voltage fluctuation range ± 15% 15. Adopt back-in-front-out wiring for power unit 3 phase 3.3KV/6.6KV/10kV 315kW-7100kW |
