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, shown below, before
installing the DC reactor.
Note: 115V models have no DC choke.
