Thanks to autotransformer technology, it delivers a well-regulated output voltage to your fan, ensuring smooth motor operation and extending the fan's lifespan. Using the external rotary knob on the device, you can select from 5 speeds. An additional 230 VAC output is provided as soon as the rotary knob is turned from the zero position.
