Speed Controllers

VA Series, EP Eziplug & USD Series Speed Controllers

Speed Contrllers

VA Series Speed Controller
The VA series of speed controllers offers a comparatively low cost option for varying the flow, power consumption and sound levels of single phase fans with a current rating of up to 10 amps. Speed control ranges from 100% down to approximately 50%.

VA speed controllers are recommended for 240v external rotor motor fans to ensure adequate cooling under speed control conditions. They should not be used to speed control fans with conventional foot or flange mount single phase motors other than models designated as being speed controllable.
