This sine filter is an option for the Altivar range of variable speed drives. Its nominal current is equal to 400A. It is used as an output filter (between the drive output and the motor) and allows your frequency converter to operate with motor cables longer than the maximum allowed lengths. Its protection class is IP00. It weighs 190 kg. It is used for applications that require long cable runs, motors connected in parallel, dv/dt sensitive submersible pumps and an intermediate transformer between the drive and the motor.
