DC Output Reactor
A 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).
Install the DC reactor between terminals +1 and +2. Remove the jumper before installing the DC
reactor. See the figure below.
NOTE: 115V models have no DC choke.
