DC Reactor
DC reactor can increase the impedance, improve the power factor, decrease input current, increase
system's capacity and decrease harmonic which generates from AC motor drive. Furthermore, DC reactor
can steady the DC voltage of AC motor drive. Compare with the reactor which sets up at input side, it is
small, lower price, and low pressure drop.
Method of set up
DC reactor sets up between +1 and +2 of the circuit, and the jumper should be removed. See
the figure below:
