Allen-Bradley reactors help keep equipment running longer by absorbing many of the power line disturbances that can shut down your drive. Allen-Bradley isolation transformers can provide both voltage change and isolation for your variable speed drive. These designs are harmonic compensated and IGBT protected to help assure optimum performance in th...
Multiple drives on a common power line should each have their own line reactor. Individual line reactors provide filtering between each drive to help reduce any crosstalk while providing optimum surge protection for each drive.
When multiple motors are controlled by one drive, a line reactor can typically be used between the drive and all of the motors. Size the line reactor based on the total motor/load horsepower.
Selecting the correct impedance rating is critical for your job. An impedance value that is too low may not limit peak current. An impedance value that is too high may reduce input voltage. Allen-Bradley line reactors offer two impedance ratings.
Voltage spikes on AC power lines can cause elevation of the DC bus voltage, which may cause the drive to trip on an overvoltage condition. 3% impedance reactors are effective at helping to protect drives against voltage spikes and spurious tripping. Allen-Bradley line reactors absorb these line spikes which help protect the drive from spurious trip...
Allen-Bradley load reactors can help protect motors from high peak voltages. For IGBT drive applications with long drive-to-motor lead lengths, Allen-Bradley load reactors can help protect against fast dv/dt rise times.
