Thank you for the quick reply Nick. Will it still accept up to 15V(I think that was it) and if so, may I lower amperage respectively?
-
If we were to use a power supply, what are the new specs for that? If I use a 12V PSU, how many amps should it handle?

Possible board cooling methods?

Oh, that looks pretty cool. Looks like the sinks are also mounting the board in place. I'm curious now, gonna do some temp probing to see if that'd be worth it. BTW, I'm not looking to run 200w a lot except that right now I wan't to stress the PSU to see if it warms up. -

Oh the inductors? I thought the fets would be the heaters. Wasn't sure if someone like alpine or another diy shop might have made something. I know heat & longevity are linked in electronics and my PSU doesn't even get a little warm. So cooling the board was my next priority. Thanks for the reply. -

So, I finally finished building my desktop DNA200 mod. When doing 200w testing though, the board heats up quite fast. Board is in an alpine A+ enclosure. PSU is 12V stable. a look: https://www.instagram.com/p/BGqocbuD8hV/ Does anyone have recommendations for cooling this board? -
Oh, I see now. The resistances specified for Ni are for Base value and not the high value it will hit during usage. Brilliant!
-
Yeah I just noticed in Ni-mode it won't rise to the .9ohm @ 40w the device should be capable of. That is strange. I don't use Ni myself anymore so that's moot benefit for me. I'm in the SS316L FTW camp. In and out of TC, SS tastes wonderful.

Yeah, I keep a DNA40 handy now for just such purposes. I can't say I'm happy that super subohmers won out over much less current hungry higher ohm builds. DNA's being able to fire a screwdriver isn't news to me. lolol. Either way, I have the perfect enclosure for the 75 that will be parallel 18650.

Looking at the spec sheet we see a 6V max for the DNA 75 while the DNA 40 goes on up to 9V. So on the DNA 40 you can get 40W@~2ohms While on the 75 you can get 40W@.9ohms and on the 200 you can get 40W@~2ohms Is there a reason for limiting the upper voltages other than power saving?
