DC Reactor
A DC reactor can also increase line impedance, improve the power factor, reduce input current,
increase system power, and reduce interference generated from the motor drive. A DC reactor stabilizes
the DC bus voltage. Compared with an AC input reactor, a DC reactor is in smaller size, lower price, and
lower voltage drop (lower power dissipation).
Installation
Install a DC reactor between terminals +2/DC+ and +1/DC+. Remove the jumper, as shown in the
figure below, before installing a DC reactor.
