These autotransformers are efficient, trouble-free devices for controlling AC voltage and any other quantities that derive from AC voltage: heat output, light intensity, motor speed, and power supply outputs.
These continuously adjustable autotransformers are unlike most transformers. Units have a transformation ratio that can be smoothly and continuously changed so that the output of the unit can be controlled from zero to line voltage or even higher.
