An auto transformer is a compact, cost-effective electrical device that uses a single winding to perform the functions of both the primary and secondary windings. Unlike conventional transformers, it features a direct electrical connection between input and output, allowing for efficient voltage regulation by tapping into different points on the winding. Known for their efficiency and reduced losses, auto transformers are widely used in power systems, boost converters, industrial machinery, medical equipment, and telecommunication setups.

Manufacturing Range: Up to 200 MVA, 220 kV Class
