Help me build a large CXA3070 Rig

Bonjour
Why don't you buy a 12V 1A universal psu...dimable from 4.5V to 12V...and cheap (8$)
That is what i use and it work very well...4.5V in winter and 12V in summer...
Have a great day★

But how many fans will that be good for? I need to power four fans x three. 12 total, divided on three different bars. I just want it to be easy and neat.

My fans are 250mA I guess...so 4 =1A.
It depend on your fans!

What did you end up with for powering four fans? I need to do the exact same thing, just to power some different fans, but same same, it would seem. Please do let me know, this is my main concern for the time being. Thanks

I went with the APV-12-12. So, 4 per driver.

well actually the hlg case is anodized, so you have to touch the driver in just the right location to be grounded.

I did a quick continuity test between the ground and the shell and got a positive result. Not sure the anodizing creates much resistance?

robincnn tested and found the shell to be non-conductive. to be safe I still attach green wire to
my heatsinks\chassis.

I did the test as @salmonetin suggested with multimeter.
The meanwell HLG-120 chassis is grounded but metal case is anodized and non conductive.
There are 3 or more small hexagonal shapes that pop out at bottom and are conductive, if these touch heatsink then its grounded
also screw might likely chip away a little anodized layer so very likely heatsink grounded too. But good to check.

Lol...you did the little animation in french...cool (maybe not...)
I asked cause I want to know how much you pay in $! I always have the price in €!
7.73 €...9.60 $ not so expensive...is it dimmable with a pot?

You can create a dimming circuit with anything, really. If you want to dim, I'd recommend getting a fan controller like this -

awesome, thanks I trust a MW driver more than a cell phone charger I dont want to cut any corners or be cheap on any parts besides prefering the cxb3070 over the cxb3590. The savings are buying the fans'heatsink combo. quite nice.

Bonjour
Did you try the APV-12-12 already!?
Is it getting hot like a hlg-185-1400?
Maybe I will try this one with the controller for my next build...I wait to see how my dimmable 12V adapter works cause it is half price and work perfectly nice since now (X fingers!) And didn't get hot (barely)
Have a great day ★

 

[HockeyBeard]

I haven't put it together yet. I've got to acquire a couple tools to finish the build how I'd like. I decided to go the fence post route. I also still need to grab a molex adapter to power the fans. Pics to come.

I hope it works well. The APVs are very cheap, and Jerry sells them. I asked yesterday. He sells them at 4,5 USD. Seems like an easy solution and a good price for a meanwell product ! Have a nice day everyone

 

[littlejacob]

Bonjour
Wow!...holy Jerry!!!
He have almost everything...
I wonder why he do not sell complete package with all parts to build panels!?
Wirez, wago, fans, TIM, heatsink...we should suggest that to him! Isn't it a good idea!?
Why he didn't do it already?
Practical for us and more money for him!
Have a great day ★

I've been waiting on lenses for over 2 weeks. There was the Chinese holiday and then a week after it ended I inquired about the lenses I had ordered. He told me he was out and waiting on the factory to make more. Still haven't heard back yet. You guys are pushing their production capacity to the max!!

 

[HockeyBeard]

@SupraSPL

I was wondering, if I wanted to use Heatsink USA sinks, cut to approx CPU size with a 120mm fan on it, what profile do you think would be ideal?

Whaaat! a holiday, that's outrageous. dont they know that they work for Us.

 

[Rahz]

That's what I said! Jerry was not pleased.

@HockeyBeard how's the big build coming along? Have you ordered anything as yet? Believe me, I understand how much longer everything takes with a bigger panel!

Yeah, the space is still being allocated in a garage and isn't moving as quickly as I'd like. I've pretty much decided to do modular bars, or maybe a couple 4x4 fixtures. Some funding is going to have to come from this run to help pay for all the parts though. If I'm going to go with all cxb3590, that's a nice little chunk... The devil is in the details.
