Autotransformers are electrical transformers with single coil. Via their different voltage taps, reduced voltages are available. The single winding of an autotransformer acts both as primary and secondary winding simultaneously. This results in a smaller and lighter construction compared to classical dual-winding transformers. Autotransformers are integrated in Sentera transformer fan speed controllers. You can also use them as a separate component in applications that require a voltage reduction. Sentera has its own production line for autotransformers to guarantee optimal quality.
