The CFW10 and CFW100 have been replaced by the CFW300 series - learn more here.

Effective July 1, 2017 the Weg CFW10 series is considered non-stock. The replacement series is the Weg CFW300 series; smaller footprint, more features and the exact same price! To learn more read our blog introducing the new and improved CFW300!

WEG CFW10 series is a low cost option when you need to operate a three phase motor where only single phase power exists! 

The Weg CFW10 will take either 120V (SA model) or 230 volt (SD model) single phase input power and convert it to three phase, 230 volt without the need for a transformer.

Programming is made easy with a keypad and bright LED display and can operate in ambient temperatures up to 122°F (50°C) without de-rating. The CFW10 is a simple, rugged drive that will give long lasting performance in the most extreme conditions.

This drive is great for applications such as:

  • General Machines
  • Centrifugal Pumps
  • Processing Pumps
  • Fans / Exhausters
  • Stirrers / Mixers
