Variac

[Mark Hughes]

>The Variac can provide isolation (as in DC isolation), however it has been my
>experience that Variac can cause some noise at various harmonics. This noise
>is usually very slight. Most Variacs have some current limiting properties.
>So what this means is if you isolate after the Variac you will eliminate more
>noise and cause less current loss.
