Ac / Dc Reactor - Delta C2000 Plus 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, increase system capacity, and reduce interference generated from
the motor drive. It also reduces momentary voltage surges or abnormal current spikes from the mains
power, further protecting the drive. For example, when the main power capacity is higher than 500 kVA, or
when using a phase-compensation capacitor, 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 between the main power and the three input phases R S T, as
shown in the figure below:
