The V1K consists of two major components. The first part of the filter is a series line reactor which dampens the voltage distortion on the output of the VFD. The second component is a snubber circuit which effectively reduces the voltage distortion, dV/dt, to 1,000 volts per micro second on a typical 480 volt system. These two components are very effective at protecting the electric motor and the affects of dV/dt on the output side of the drive.
