1321 Line Reactors, Output Filters, Isolation Transformers, Common Mode Chokes and DC Link Chokes

Don't ignore the cost of power line disturbance. Allen-Bradley 1321 Reactors and Isolation Transformers can contain it!

The Benefits:

• Allen-Bradley reactors help keep equipment running longer by absorbing many of the power line disturbances which can shut down your drive. Allen-Bradley isolation transformers can provide both voltage change and isolation for your variable speed drive. These designs are harmonic compensated and IGBT protected to assure optimum performance in the presence of harmonics.
• The 1321 Reflected Wave Reduction (RWR) output filter, when installed with PowerFlex 70, 700, 700H and 700S drive and motor combination, will allow the user to install the motor up to 1200 feet away from the drive. This filter is intended as an "at the drive" alternative to the patented Bulletin 1204 Terminator. The 1321-RWR reduces the possibility of AC motor stator winding insulation failure due to induced corona or partial discharge damage from high transient peak Reflected Wave voltage spikes associated with long inverter-to-motor cable lengths.
• The 1321-M Common Mode Choke Options can be installed with 1305, 1336 Plus, 1336 Plus II, 1336 IMPACT™, 1336 FORCE™ and PowerFlex® AC drives. When installed at the drive output the common mode choke helps to guard against interference with other electrical equipment (programmable controllers, sensors, analog circuits, etc.). In addition, reducing the PWM carrier frequency reduces the effects and lowers the risk of common mode noise interference.
• 1321-DC DC Link Chokes can be installed with Frame C PowerFlex® 40, PowerFlex40P and all PowerFlex® 400 drives. Add DC Link Chokes in series with the internal DC Bus to:
  • Reduce AC Input Line Harmonics
  • Help meet IEEE-519 limits
  • Absorb Voltage/Current Spikes
  • Reduce AC Ripple on DC Bus
  • Reduce dV/dT and dI/dT rates
  • Solve nuisance overvoltage tripping
  • Reduce DC Bus Transient Overvoltage
