Our customer's first choice for AC speed control of single phase motors! For use with resistive loads, permanent split-capacitor, permanent split-phase or universal motors. Ideal for small blowers or lighting applications!

Triac Controls adjust the voltage output of an AC supply, similar to a light dimmer or ceiling fan control. Wen applied properly, these triac controls can be used
with single phase AC motors to adjust their speed. They can also be used with resistive loads such as lighting.

It is important to note Triac Controls will NOT work with capacitor start motors, a common motor for single phase applications. Capacitor start motors are not designed to be run variable speed. Visually, these motors have a large hump on the top or side which houses the motor capacitor. Trying to slow these motors will be stopped by the motor capacitor.

Motors which may have their speed adjusted using these triac controls are Permanent Split Capacitor (PSC), Permanent Split Phase (PSP), Shaded Pole and Universal. These are all single phase motor types which might adjust speed using triac controls- these applications may still have limitations.

It is not likely a triac control will offer a wide range of speed adjustment - it likely will be in the top half of speed pot adjustment. The user may need to turn the triac control output up to get the motor moving before slowing down. We recommend testing these triac controls with your application.
