Line Reactors
RM Series - Line Reactors
Due to the attenuation of line disturbances, the life of your solid state devices are extended when protected by the use of a HPS line reactor.  Line reactors, when selected for the output of your drive, will enhance the waveform and virtually eliminate failures due to output circuit faults. 
RC Series - DV/DT Filter Reactors
The HPS RC series DV/DT filters are specifically designed for drive/motor applications with long lead lengths (usually where the motor cable length is 20 feet and greater).  They should always be installed next to the IGBT variable frequency drive.
