Variacs

Variacs

Variacs are adjustable transformers commonly used in electrical equipment to control voltage levels. These devices are essential for testing and regulating the output of power supplies, motors, and other electrical components. Variacs operate by adjusting the turns ratio of the transformer, allowing users to increase or decrease the voltage output as needed. They are versatile tools suitable for a wide range of applications, including electronics testing, industrial equipment calibration, and laboratory experiments. Variacs are known for their precision and reliability, making them a popular choice among engineers and technicians working with electrical systems.
