Description
The simplest way to adjust and controls the speed of your AC fans. This then ensures a longer life of the fan motor.
It has variable speed control and full power and off and is suitable for up to 300 W.
Note: this type of fan controller is a resistance based controller. All resistance based controllers may cause a humming noise from AC extractor fans. EC fans do not have this issue and have much more capable controllers to reduce speeds with zero additional noise.
