The LR2 line reactor series adds seven new frame sizes to match all GS, DURApulse and WEG drives, and a variety of other VFD brands. Line Reactors (from $48.00) are used on VFD line inputs to protect the drive from current spikes created by the VFD. On VFD outputs, line reactors protect motors, allow cooler running, and are recommended for any motors where wiring length is less than 100 feet. For wiring distances over 100 feet, the VTF series output filter is recommended. Starting at $329.00, VTF (voltage time filter) series output filters combine line reactor and resistor-capacitor filter circuit to provide protection against voltage wave reflection, especially on long motor cable runs up to 1,000 feet. VTF filters, by increasing voltage rise time, limit voltage spikes from exceeding 1,000V to protect cable runs and reduce motor heating, noise, vibration and insulation breakdown.
