DC reactor
DC reactor can also improve the power factor, reduce input current, and reduce interference
generated from the motor drive. A DC reactor stabilizes the DC BUS voltage. Compared to an AC input
reactor, the advantages are smaller size, lower price, and lower voltage drop (lower power dissipation).
Installation: Install the DC reactor between terminals +1 and +2. Remove the jumper, before installing the
DC reactor.
Note: 115V models have no DC choke.
