Input and output line reactors are available for DURApulse Drives

• Input line reactors 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.
  
  
• Output line 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. They are recommended for operating “non-inverter-duty” motors and when the length of wiring between the AC drive and motor exceeds 75 feet.
  
  
• NOTE: If you purchase an AC line reactor with your AC drive order, you'll receive an an extra year of warranty coverage in addition to the standard warranty period.
