Allen Bradley, 1321 2A Sine Wave Filter

The Rockwell Automation reactor help to keep equipment running longer by absorbing many of the power line disturbances that can shut down your drive. At the input of a drive, a line reactor helps protect against surges or spikes on the incoming power lines and help reduce harmonic distortion. Each power line should have their own line reactor. Individual line reactors provide filtering between each drive to help to reduce any crosstalk while providing optimum surge protection for each drive.

Maximum switching frequency is 20 kHz
Compensated for the additional currents and high frequencies that are caused by the presence of harmonics
