3PN Series, Variable Transformers

Variable transformers, also known as adjustable voltage transformers or variacs, are versatile devices that enable users to select a desired output voltage while maintaining a consistent amperage rating. These transformers feature a single voltage winding that is tapped at different points to provide multiple output voltage options. Variable transformers are available in various configurations, including bench or panel mount designs with receptacle or terminal output options. They can be equipped with plug or terminal input options to suit different installation requirements. Moreover, these transformers are offered in a wide range of supply and output voltage options, ensuring compatibility with diverse electrical systems and applications. The primary advantage of variable transformers is their ability to provide adjustable output voltages without compromising the amperage rating, making them suitable for applications where precise control over voltage levels is required. This flexibility allows users to fine-tune voltage settings according to specific needs, such as in laboratory experiments, testing equipment, or powering sensitive electronic devices. Benchtop variable transformers are commonly used in research and development laboratories, educational institutions, and industrial settings. Panel mount versions are often integrated into control panels or machinery for convenient access and operation. Regardless of the configuration, these transformers offer reliable and efficient voltage regulation capabilities. In summary, variable transformers are valuable tools that allow users to select desired output voltages while maintaining a fixed amperage rating. With their various mounting, input, and output options, as well as the ability to cater to different supply and output voltage requirements, these transformers find applications in a wide range of industries, providing precise voltage control and ensuring optimal performance of electrical systems and devices.
