This sine filter is an option for the variable speed drives of the Altivar series. Its rated current is 400 A. It is used as an output filter between the inverter output and the motor, allowing the operation of your frequency inverter with motor cables that exceed the maximum allowable lengths. The protection class is IP00. It weighs 190 kg. It is used for applications that require long cable runs, parallel-connected motors, dv/dt-sensitive submersible pumps, and an intermediate transformer between the inverter and the motor.
