CO = Carbon Monoxide (hence the lack of the implied subscript of the numeral 1) and CO2 = Carbon Dioxide (hence the subscript 2 meaning dioxide)... I could post subscript but I don't want to show off. I can't tell you how since I swore not to tell anyone or else I'd have to whack you.

Didn't I say that?

And now look what you did here I am alone on this page!!!

Bigwink

And that?

CO
... too

CO2

H2CO3 = big time acid = will really irk you! Actually burp you..

Irk.... or burp... either way it ain't fun.

Don't trust atoms, they make up everything.

Would have PM'd SD2 but can't Sad

That understandable since by the term "dimming" it implies that the controlling action that adjusts the output power delivered to the humidifier is depending on a voltage waveform clipping (aka limiter) circuit. When clipping a modified waveform it would be difficult to determine what energy value would result prior to the clip as versus a pure sine wave. It could be higher or lower depending on the rise time and overall shape of the waveform before the clip. Since voltage is the determining factor for actuating the clip, power delivered has no say in the process and could be delivered higher (or lower) than intended (were talking watt-seconds here).

I suspect it would be higher in most cases since for a run of the mill generator's voltage regulation scheme to work properly would require the generator to supply an excessively high voltage and then clip it at the 120 volt level. That would yield a modified waveform output (flat topped) with a higher average power content as opposed to a pure sine wave output.

It would be nice if the manufacturers of these devices would recognize the importance of running them from a generator on occasion and give some "up front" guidance in the documentation that is given to the users.

EDIT: BTW, Ghost1958, Thanks for taking the time to research this and sharing it here. No doubt it will put some minds at ease.

Thanks SD2 for getting this back on topic. You're my herogreatest master!!!

If you're not part of the solution, you're part of the precipitate.

What a boo boo I made, what a cover up, sheesh, getting old losing my mind.....
