Auto transformers are efficient electrical devices used to regulate voltage levels within power transmission and distribution systems. Unlike conventional transformers, they use a single continuous winding to function as both primary and secondary, resulting in a more compact design, improved efficiency, and lower losses.

Powerlite Electricals Private Limited manufactures high-performance auto transformers designed for utilities, substations, and industrial applications. Built using advanced engineering and strict quality controls, our auto transformers provide reliable voltage control, improved system stability, and long service life, while meeting national and international standards.
