220 V AC motor speed controller

The Ruth's sister SS-22 is a new internal power cable assembly that integrates a 20 kΩ potentiometer, capacitor and dial. It regulates single-phase AC motors at 220 V and 50 Hz by varying the voltage supplied to the windings.

Suits hobbyists and technicians adjusting fan

Builders needing three-phase control, variable-frequency drive features or higher voltage ratings should look elsewhere. The unit is designed only for the specified single-phase 220 V 50 Hz supply.

Questions about this item

What mains voltage and frequency must my supply match for this SS-22 controller to operate?

The controller is rated for 220 V AC at 50 Hz, so your supply must provide exactly that voltage and frequency.

Will the included 20 K Ohm potentiometer work with an older single-phase AC motor I already have?

Yes, the 20 K Ohm potentiometer is designed to regulate compatible single-phase AC motors within the controller's 220 V 50 Hz rating.
