So, you are saying that when the oscilloscope registers a peak of 9.6v (as it did for fazed and pbusardo), that 9.6v didn't actually enter the circuit? No matter how brief the time, the scope registered that as a peak while loaded. Only the average between peak of 9.6 and 0v (the bottom on both their scopes wasn't much above 0 - not sure why I typed 3, maybe because that's where pbusardo had his set when he was hitting 9.6v peak... must have been on my mind)...
No. If the peak was scoped to be 9.6v with a 1.5 ohm resistor load on the circuit, that doesn't negate ohms law because it happened in pwm and there is an average to be considered. The average is actually not to be considered when calculating the max amps. Calculating max amps, the only thing to consider is the load and the peak voltage.
Fazed was pretty tough on the device and maybe even unfairly so... but then it did fail, so maybe not unfairly so. Tough to say. pbusardo was much more positive, but his didn't die during the same testing. He did note that the pwm was not acting as expected (he stopped short of saying malfunctioning, but did say poorly tuned). And, he probably should have compared his numbers etc with the jokerAV he has instead of the provari since the jokerAV uses the same sort of regulator.
No thanx, I think Ohm's law is good. LOL.
Maybe our problem is the definition of "switch" to me this means the momentary push button switch being used to fire the device (or to do the provari jig on to get to the menu). I'm saying the current draw through that switch is WAY under 1A. Most any DC to DC regulator with more than 3 pins has a low current 'inhibit' pin that controls turning the output on and off. I am assuming that the fire button/switch is connected to that and there for has very little current going through it.
The regulator itself might be doing 6A. Still not a biggie though. My 6A rated OKR regulator doesn't do current limiting until 9.8A and recommended fusing is at 10A.
Correct me if I'm wrong but it appears that the 9.x P2P voltage includes that little micro peak on the leading edge of the wave?? It's hard to see. I'm more interested in what the flat top of the square wave is at. I would expect that to be at the input (battery voltage) or around 8.4v. That would really be the better number to use as that little peak is of such short duration it's not going to have a big effect. IF I remember correctly back when O-scopes where large things on a cart with tubes in them we were taught to calculate P2P voltage based on the flat top/bottom on a square wave not the trigger spikes.
Agree it would've been nice to see the JokerAV thrown in there or that other one... SRV, SVR.. can't recall it's name. Sorry, to me, Phased came across as a paid soldier of the Order (GOOP) in this one.
I could care less if they sell 1 more VMax or Provari. In my mind I saved $100 and got something that's close 'nuff. We all know, one's reality is all in one's perception ;-)
With that said I think it's time for me to retire from this thread.
