Key Features
Conversion efficiency up to 98%, saving hydrogen consumption
It has a wide DC voltage range ( 400 ~ 850VDC )
Reliable and stable speed/position sensorless vector control algorithm
High control precision, fast response speed, and comprehensive protection functions
The output frequency can reach 0~ 3500Hz , and the maximum motor speed can reach 210000rpm
The low harmonics in the output current effectively reduce motor heating
The output dV / dt is small, which effectively reduces the motor shaft current and protects the motor insulation life
