3 phase 3.3KV/6.6KV/10kV 315kW~7100kW
- High integrated technology and completely digital control system, good anti interference ability.
- Control system power supply redundant design.
- Multi monitor for power units
- Power unit bypass function to achieve power unit redundant design.
- Standard RS485terminal to communicate with DCS.
- More than 30 kinds of protection for inverter, motor.
- Full parameters record, temperature and DC bus of each power unit can be monitored and indicated in display.
- High efficiency=98% and power factor=0.96, low harmonic design<2%.
- DSP control system optimize modulated waveform to ensure perfect waveform without harmonics
- Better energy saving function. Self-regulation for voltage when detecting light load to save energy.
- Big voltage, current margin design.adopt 1700V IGBT, twice voltage margin, twice current margin
- 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
- Speed trace function
- Wide national grid voltage fluctuation range ±15%.
- Adopt back-in-front-out wiring for power unit.
