Meanwell LDD driver: for those who want to dim to 0 using Arduino

I have interest in such a dimmer -- I won't have a controller with which to test my light build for a while, and would like to test as I go.

I don't suppose you have one you'd part with...

... or lend ...

LOL. I haven't even run the CAM processor on this design yet! I'll probably finish cleaning up the design over the next couple of days and then put in an order for 10 boards, so I'll send you one when I get them. I know of only a few people that are running led lighting that don't already have a controller. They're Old school "Knob Users" so I'll have to include YOU in that group until your controller is completed.;)

Typically they look like this-

what are the seach parameters? Best I find is the ones w/ "free ends".. not a problem just not "efficient"..

LDD PCB Choice

LDD PCB Choice

Hi All,
Clif here. Just getting back to my LED
build after a long interruption, it seems the driver scene has changed.
My build is 72 Cree LED's mounted on 4 1"X 36" heat sinks, 48 RB, 18 CW, and 6 NW. My power supplies are Meanwell SP-320-48, 48V 6.7A. My order for 5 LDD-1000H drivers and the frames to mount them just arrived. Now what PCB to go with. I have been looking at O2's 5 up, the 6 up boards, the two with integrated controller, the more choices the harder the decision. Now O2 has posted a manual add-on for control that looks interesting coupled with a 6-up board. That would put the programmable controller off for another day, and get me up and running sooner. I hope. If anyone has any thoughts or advice they would be appreciated. Thanks,
Clif

Yes i like that one.. "blinkys" are a nice touch, Only thing I need to figure out is the pin out on the Typhon board, since it looks like it could be plugged in 2 different ways.. one that makes sense (USB out up) and one that doesn't. ;)
I don't see a pin out labeling on the Typhon..

If your Typhon isn't labeled then use a multimeter to locate the GND (ground) pin. Once it's location is determined, use that info to orient the 6 pin FTDI adapter correctly. Easy peasy.

It may be labelled but the LCD is in the way..

50/50 chance right.. LOL...
found ground.. the adapter would point up... ;)
 
What are folks using to house the LDD boards? I was going to mount mine on a MakersLED Heatsink but would like to cover it in something somewhat protective since that will be hanging over evaporating salt water.

Which LDD board are you using? If it's 100mm wide, it'll fit the top slot on the makers heatsink and get the benefit of forced air cooling from the fan. Since the top side of the heat sink isn't as exposed to salt spray as the bottom, condensation shouldn't be an issue either. Here's how I'm mounting mine- either way will work.

That's perfect, now I feel stupid. If you used the little PWM converter you sent me where would you mount that as it is significantly smaller. I guess I could mount it to a 100mm acrylic sheet and do the same as the LDD.
 
Have ordered up a few of the 5UPs, can anyone advise me which pin sockets to get (seen a few sizes mentioned).
Just need to get some screw terminals for it now, what size are the holes for them?
 
I paid 37 cents a piece for them locally. each unit has 2 screw terminals. I know that was too much but I got them instantly. :)
