AC Line Reactors for GS Series Drives (VFDs) - Legacy Series

There are two series of AutomationDirect line reactors that can be used with GS series AC Drives: the newer LR series line reactors and the original GS series reactors (legacy). New applications should use the LR series of line reactors for cost savings. The legacy reactor parts will only be available for a limited time (until they are out of stock).

Line reactors used on the input side of a drive protect the AC drive from transient overvoltage conditions, typically caused by utility capacitor switching. The input line reactor also reduces the harmonics associated with AC drives. Input line reactors are recommended for all installations.
Line reactors used on the output side of a drive (load reactors) protect the motor insulation against AC drive short circuits and IGBT reflective wave damage, and also �smooth� the motor current waveform, allowing the motor to run cooler. Output reactors are recommended for operating �non-inverter-duty� motors and when the length of wiring between the AC drive and motor exceeds 75 feet.
