After the positive experiences with the energy-efficient variable speed control of three-phase fans, the Multifan Intelligent Fan Drive is also well-suited for single-phase fans. This results into a unique fan drive, which functions optimally with both versions.

The single-phase version has some specific advantages:

• Because of the FAST™ software, an energy-efficient control is possible.
• The Intelligent Fan Drive with the fan fits perfectly in companies that have traditional single-phase supply
• The fan cannot turn in the wrong direction
• Extra isolation in the windings is not necessary anymore with the use of the Intelligent Fan Drive for both single-phase as well as three-phase fans
• The Intelligent Fan Drive can be used as a replacement of traditional controls such as triac or transformers.

The optional override switch is well-suited for single-phase and three-phase fans.
