Re: Duty cycle of OBIT?



Original poster: "Jonathan Peakall" <jpeakall@xxxxxxxxxxxx>

Hi All,

While what everyone said about the duty cycle of an OBIT is true (IE they
are for a brief start up) I have used on for a jacob's ladder for hours at a
time. The transformer got good and warm, but not outrageously hot. I have
done it a number of times to the same obit and it is still alive and
kicking. The same obit probably has about 20 hours of tesla coil use as
well, on my very first coil where I was doing almost everything wrong.

This is not to say that all obits will take this kind of abuse. But I did
want to say that I have tortutred one severly, and it survived.
