Ac / Dc Reactor - Delta CP2000 Series User Manual

7-4 AC / DC Reactor

AC Input Reactor
Installing an AC reactor on the input side of an AC motor drive can increase line impedance, improve
the power factor, reduce input current, and reduce interference generated from the motor drive. It also
reduces momentary voltage surges or abnormal current spikes. For example, when the main power
capacity is higher than 500 kVA, or when using a switching capacitor bank, momentary voltage and
current spikes may damage the AC motor drive's internal circuit. An AC reactor on the input side of the AC
motor drive protects it by suppressing surges.
Installation
Install an AC input reactor in series with the main power to the three input phases R S T as shown
below:
