CVT

A constant voltage transformer (CVT), also known as an auto-transformer, is an electrical device used to regulate the output voltage of an alternating current (AC) power source. It works by continuously adjusting its output voltage to maintain a stable and constant voltage level, despite variations in the input voltage.

CVTs are commonly used in applications where a stable and constant voltage is required, such as in laboratory equipment, computers, and sensitive electronics. They are also used to power low-voltage devices, such as lamps and motors, from a high-voltage power source, or to convert a high-voltage AC power source into a low-voltage DC power source.

CVTs are designed to be compact, efficient, and cost-effective, and are widely used in a variety of industrial and commercial applications. They typically consist of a primary winding, a secondary winding, and an electronic controller that monitors and adjusts the output voltage. Some CVTs also include features such as over-voltage protection, short-circuit protection, and thermal protection.
