Electrical Auto Transformer - Frequency (Mhz): 50-60 Hertz (Hz)

An electrical auto transformer is a compact and efficient device used to adjust voltage levels in electrical circuits. Unlike conventional transformers with separate primary and secondary windings, an auto transformer has a single winding that serves as both the primary and secondary, with a variable tapping point to provide different voltage levels. This design allows for a more compact and cost-effective solution while delivering good voltage regulation and power efficiency. Auto transformers are widely used in applications where a small voltage adjustment is needed, such as in motor starting, voltage regulation, and in educational or laboratory settings. They offer high performance with minimal energy losses and are particularly valued for their simplicity and reliability in applications requiring continuous voltage changes or precise control.
