electronic flour. ballast ?

[Copperclad]

I have been told that once you apply a certain voltage on a multi-tap flour. electronic ballast, it now "remembers" this first applied voltage and chaging it to a different system,,,say from 110 to a 277 install, that it would destroy it.
Have any of you heard of this?

sorry to admin if this is not posted in the correct place

Most of them you can completely disconnect the neutral and the hot, then be able to reconnect to the new voltage. Some of them get confused on voltage input, and have to be reset this way.

I suspect that this information is false.

Our supply house usually stocks Advance Centium w/ IntelliVolt technology ballasts for regular ol' 4' T8 lamps and the like. This is a spec sheet for this ballast (read section 2.4):

No mention whatsoever of the ballast "sticking" to whatever voltage is initially supplied. I think you could take a ballast from a 120V supply, truck it across town and put it in a 277V supply and it would automatically do its thing just fine.
