Thanks, it's just a front end on their simulator, with some digitized spectrum chart data hacked in to do the efficiency calculations. There's also lots of actual measurements spread around the site, but spread is the key word there.Good job on those charts
I mean the 240 would work. If you're American this might not help at all, but it's probably worth it to wait and see what kind of voltage the ELG-C200 runs.
the voltage over a cob holder can never exceed the voltage of the cob inside the holder.
I am literally too high to know what this means. That is all.
good thing we dont need to. even the 100V 3618s can be safely run a dozen or more at a time in parallel, off a single power supply and still be in spec
My own measurements of vF between cobs running in series say this is probably fine. The cobs I've checked are really well matched, but I'm still hesitant to just say "run parallel" to everybody who asks. Current hogging and thermal runaway are actual things.
As are fuses...
Not to throw a wrench in here, but I did the math 4 1212's required more voltage (147) then the meanwell 1400 could supply. This is why I special order 1300 am drivers from LSD, so I could exactly what you are talking about and not over drive the drivers. I ended up having to buy 20 to make the deal, but hell I needed 18 to do my room so now I have 2 spares. I didn't feel comfortable overdriving the 1040 even though many here say it can be done. My 2 cents.
i think he forgot the word when and meant except when there is no cob in the holder. serial circuit, so like the cob inside it, the holder doesn't get the total circuit voltage.
You are right, obviously, the voltage between the +/- contacts on the holder won't exceed the voltage drop of the cob, but I believe the unresolved question is arcing between the heat sink and high voltage line, for instance.
what does that mean, like soldering to an eggshell, can you break the cob or something?
echoed for truth, thanks Jorge for this thread.Yeah I could see you would of had to put a load of work in to get those figures, sometimes when people see the end result they think it came easy, clearly you have put some serious hours into this so well done and thanks
I hate to be a downer but isn't 20 x1212 @1400mA (50w each) 1000W total?! I call bullshit on 5-6lbs per run.
he didnt say 1212
Oh he definitely meant 1212s. He's been asking how it's possible to run 4 1212s on a 200W driver for awhile now.
As Jorge said, all the preceding talk was about 1212s.
