The VPhase I believe regulated the voltage to 220V. The one I fitted
today has no such mechanism. It basically is a tapped transformer that
gives 6, 8 or 10% voltage (or claims to) voltage drop.


We used to have an auto version of that device in TV studios in the '60s
to regulate tech mains. But could up the voltage as well as reduce it.
