Altivar AC Line Choke

A line choke can be used to provide improved protection against overvoltages on the line supply and to reduce the current harmonics produced by the drive. The recommended chokes can be used to limit the line current. They have been developed in line with standard EN 50178 (VDE 0160 level 1 high energy overvoltages on the line supply). The inductance values are defined for a voltage drop between phases of between 3% and 5% of the nominal line voltage. Values higher than this will cause loss of torque. These chokes should be installed upstream of the drive.
