KEB COMBIVERT P6 - Performance

KEB COMBIVERT P6 is a ready to market drive solution for wind Turbines of the future up to 10MW and higher.

In matters of performance KEB COMBIVERT P6 offers maximum flexibility to the user to fulfill the requirements of Speed- and torque control. The integrated Soft-PLC allows the user an unrestricted programming with the standardized programming language IEC 61131-3.

It is essential that the drive stays operational also at extreme climatic conditions (HCV and CCV) as well as LVRT ( Low Voltage Ride Through) and HVRT ( High Voltage Ride Through).

The KEB COMBIVERT P6 includes:
