3 Popular Adjustable Voltage Transformers with Digital Displays
A few years ago, we wrote a blog post describing 10 uses for adjustable voltage transformers, one of which was using it to obtain the freshest roast of coffee possible. How cool is that?
In the field of circuitry, adjustable voltage transformers are most commonly referred to as autotransformers, or simply ‘Variacs.’ Why is that? Well, in the United States, we often refer to products by the most popular brand instead of what they’re actually called. For example, kleenex and band-aids are used to refer to facial tissues and adhesive bandages. Similar to those, Variac is the brand name of one of the original variable autotransformers or adjustable voltage transformers.
If you’re looking for an adjustable voltage transformer or a Variac, how do you know which one to get? Don’t worry, we’ve done the research, spoken to customers, and put together our top three to help you narrow down the choices.

The digital displays are a nice touch. I jazzed mine up a little, and attached a digital panel meter. It will display the voltage, current, watts, and Hz. Just like having a mains meter connected all the time on the bench!
