The RTR-1 series of transformer fan speed controllers regulate the rotational speed of single-phase voltage controllable motors by varying the output voltage. They are equipped with an auto-transformer and control the speed manually in steps via a remote device, e.g. a switch or thermostat. The technology used provides a regulated output voltage with a perfect sinusoidal shape.
