The LR2 line-reactor series from AutomationDirect, Cumming, GA, has expanded with seven new frame sizes to match all GS, DURApulse, and WEG drives. The LR2 Series can also be used with a variety of other VFD brands. For wiring distances over 100 ft., the VTF (voltage, time, filter) series output offering is recommended.
♦ Line Reactors 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 operating VFD’s with “non-inverter-duty” motors, and for any motors where the length of wiring between the AC drive and motor is less than or equal to 100 feet.
♦ VTF 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 ft. 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 motor insulation breakdown.
All products in these series are UL listed. The AC line reactors have a 10-yr. warranty and the output filters have 1-yr. warranty.
