Variacs
Created in the 1930s, these AC power supplies are the most popular variable auto transformer on the market. Variacs can be used in a number of different applications — everything from vintage amplifiers to brewing coffee. These auto transformers have an internal part of their windings included in both the input and output circuit. The ratio of auto transformers can vary: the bigger the auto transformer, the smaller the ratio.
The variable auto transformers provided from Circuit Specialists Inc. vary in voltage input and output as well as size. These adjustable power supplies can be used for a number of hobbies and are very versatile. Find out which AC power supply will be used with your science lab or do-it-yourself project.
