Section 2:
2.1
Using Input Chokes
Input chokes help to protect the VFD from spikes on the incoming power supply, as well as reducing
input harmonic currents. It is recommended that an input choke is used under the following
circumstances:
•
•
•
•
Typically, the input choke will provide a significant reduction in harmonic distortion on the incoming
power supply, and will reduce the overall current into the drive cover and back pages.
