EM's selection of chokes, or AC reactors:

• Perfectly calibrated to meet the requirements of the manufacturer and compatible with all series Delta drives.
• An AC motor drive's input side can be equipped with an AC reactor to boost line impedance, enhance power factor, lower input current, and lessen harmonics produced by the motor drive.
• It is possible to stretch the output power cord longer than would otherwise be feasible by installing the AC reactor on the output side (exact length model dependant).
• It is recommended to install an output choke when more than one motor is mounted on a single VFD and is secured by manual motor starters.
