Transformer fan speed controllers

5-step fan speed controllers control single-phase or three-phase voltage controllable motors. They regulate AC fan speed by varying the motor voltage in steps. The autotransformer technology generates a motor voltage with a perfect sinusoidal shape. This guarantees quiet motor operation. A special impregnated coating reduces the electrical noise from the autotransformers. Typically, they are used in HVAC applications.
