CPX 18-pulse variable frequency drives

Demand more clean power.

The CPX series of variable frequency drives uses advanced 18-pulse clean power technology that significantly reduces line harmonics at the drive input terminals—resulting in one of the purest sinusoidal waveforms available. They prevent upstream transformer overheating and overloading, enabling the application of generators and other high-impedance systems.

Harmonic mitigation techniques can help protect equipment from potential damage, reduce power generation to overcome losses, and eliminate utility fines. Learn more about harmonics. Watch the video below.

Core features of the CPX 18-pulse VFD

  • Clean power: This cost-effective solution provides reductions in voltage and current harmonics.
  • Reliability: This VFD provides increased input protection for the adjustable frequency drive and its semiconductors from line transients.
  • Communications options: A wide range of communication protocols includes DeviceNet, PROFIBUS, Modbus RTU and Modbus TCP.
