Autotransformers are electrical transformers with one winding, featuring different taps intended for voltage adjustment. Autotransformers are the core of Sentera transformer fan speed controllers but can also be used in applications that require an AC power supply inferior to the main voltage.
230 VAC Autotransformers
These autotransformers are designed for switchboard mounting or applications requiring output voltages lower than the input voltage (230 VAC).
