Led Drivers and heatsink question for the cxa3070 build.

I mean for the meanwell led driver it doesn't come with a plug does it? or do i need to buy a plug cut it then connect tot eh wires. And i would like to connect the fans to one dimmer controling all fans.

The driver does not have a plug attached. The blue wire is the "neutral" (the bigger slot in your wall socket) and the brown wire is "line". (the smaller slot in the wall socket) THIS IS FOR U.S.A. setups.

I just cut an old grounded extension cord i had kicking around and connected it to my meanwell driver, simple and heavy duty enough.

Better off just going to wal-mart or home depot and buying a grounded plug. Less than $2, much easier to work with and you don't have to destroy a perfectly good extension cord. It's worth noting that as long as you get the ground in the right spot, you can't really mess up the wiring. The HLG series can be run on a 240v line with 2 'live' wires and a ground.

As far as placement is concerned. The PDF with 4 bars would give you the most adjustment options, but would require more fans. The 2 bar design would offer great coverage and heatsink temps with fewer fans.

I'd say go with the 2 bar design and start off with 6 vero 18's. Add the last 4 as you can afford it. If you're not planning on any automation I'd stick with the A type driver which has an internal pot to adjust. The B type has another set of wires sticking out.
 
Ty much yea I was thinking the two bar would be better I was going to run 5 on each 40 inch 4.85 heatsink. Do you think I will need two fans for those two bars. Is there a power supply unit that I can adjust the output to run those fans at lower voltage and what not. I want to drill and tap so I think I checked the screws would be m2.5

Find an old cell phone charger and cut the end off. Most are typically 5v and between 500-1000ma. There should be a label on the side.

With the vero line you'll want an M3 screws. I'd recommend a 2.8mm drill and a M3x0.5 pitch cold form(cold roll) tap, no flutes. Any sort of finish or material should work. Bright finish, High strength steel, bright finish is typically the cheapest.

Use the drill press to start the tap straight, then finish by hand.
 
Are you sure vero18 is m3 could of sworn it said 2.5. Also how long should these screws be for the heatsink I don't want to go through correct.

Yea not so much the m3 actual size but the length of it. Meaning if the heatsink base is .14 kind of hard to find a screw that won't go through. So I'm guessing if I tap through the heatsink and use a m3 screw but a longer length where it will go through the heatsink I sure that won't be a problem just want to double check to see if anyone has done that.

I drill and tap threw my heat sinks. Not much of a choice with the ones i use. Wont hurt anything. You can also use SAE 3-48 or 3-56 screws they are just .001 of a inch bigger and might be easier to find here in the states. A good source for hardware http://www.mcmaster.com/#
 
Java where did you buy your tap from did you do a forming tap.cause some taps have a h6 h4 kind of thing on them. What Size drill but did you use also TyTy
