Variable transformers, or adjustable voltage transformers, allow the user to select an output voltage while maintaining a fixed amperage rating. These transformers have one voltage winding that is tapped at various points to provide multiple output voltages. They are available in bench or panel mount with receptacle or terminal output options, plug or terminal input options, and a wide variety of supply and output voltages.
