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

[megadeth72]

I have the one made by sure with the mib6651 it's not marketed for more than 10w, i use it with 10w leds, it is just the older chip, it's a well built driver, and I'm not sure it's a knock off, they have been around for quite some time

http://www.ledlabs.ru/pdf/macroblock/mbi6651.pdf

looks like the chip can run 36v at 1000ma I have not tried, I dont have a 36v led to test with

hmm well it seems the meanwell ldd-h and ldd-l are the knockoffs, the sure drivers were on the market nearly 3 years before the meanwell drivers came out

really bothers me when people call something a knockoff when it clearly isn't

The LDD's may use the same control chip as the Sure Electronics drivers that you posted, but when the specs of the two drivers are compared, The Meanwell offering is superior to the Sure Electronics version. MY point was, If you're going to spend $5 on a driver, why not buy the most performance for the money?
The LDD is newer, and granted could very well be a "knock off" of the Sure Electronics driver. But until somebody cuts one open to identify the chip, we won't know.

dont need to the ldd-h uses the newer step down chip, the newer chip can handle more volts and amps

if your using less than 36x1000ma the sure driver should work, I don't have anything here to test that with

Has anyone tried using more than one LDD to power a high current LED yet. still haven't found any info on if they can do that.

the Sure Electonics drivers can. that's how they get the 1400ma version, they just stack two 700ma drivers on top of one another with header pins. these little boards are fun to tinker with as you can buy the one watt version and soder on additional resistors to get them up to 1050ma.

It would sure be nice if you could get higher amperage using parrel drivers with the LDDs since they are nicely water proofed! one less component to worry about when hanging over salt water!

Got my batch of dual driver PCBs last night. The package arrived 30 minutes before the tracking e-mail from ITead Studio.

Look good?

Will dust off my soldering station this week and start the build. Just missing the power supply at this point.

and thanks again O2 for the design.

That PCB looks good. You're welcome, I'm glad I could help.

Sweet.

DHL tried to deliver mine last night but I wasn't home so I will get them today I used rrasco files.I have a few extra pm me for details. If anyone has extra LDD-H please msg me.

 

[rrasco]

Good deal. I'd like to see them if you don't mind posting pics.

 

[rott]

sure will thanks for making it

 

[bhazard451]

Awesome! Mine should take another week or two.

Circumventing the restrictions on your account is not a good idea.

wish the guy would of just left them on the porch or somewhere by the door..dosnt matter I don't have the ldd drivers and every one is out of stock. I was able to find a several places in china that have crape loads of them just don't want to order 12 @ a time was some thing like $57 (4.80 each) plus shipping

Thats why I'm offering to give you some of mine for a board or two. I have some 1000HW and possibly a few 700H and 600H leftover.

 

[rott]

you have mail

 

[bhazard451]

Sweet. I can finish my build much quicker now. I'm hoping to finish the entire 60" fixture by New Years, wired and running. I cannot wait to play around with multiple LDD color channels, and lunar phases. Just bought two MP40s too, so its going to be one crazy build. Just hope the power supply works.

 

[rrasco]

Mouser still has some 600, 700, and 1000H in stock.

Mouser still has some 600, 700, and 1000H in stock.

The 700's are $12 a piece there?!

First, THANKS to everyone who is providing some thought into this and special thanks to 02 and rrasco for the board designs. Time to get my soldering skills back up to par.

I'm going to be driving a 'knockoff' dreamchip with LDD's and wanted to make sure I get things right. I'm going to order the 5 up 10x10 board but my LED chip has the following layout:

Channel 1) 10S x 2P 10000K 30-36VDC 700MA
Channel 2) 10S x 2P 455nm 30-36VDC 700MA
Channel 3) 10S x 420nm 30-36VDC 350MA
Channel 4) 10S x 2P 445nm 30-36VDC 700MA
Channel 5) 10S x 2P 15000K 30-36VDC 700MA

So, I was planning on LDD-700H's for every channel but channel 3, which I'll go with an LDD-350H on. Can I mix and match those on the 5 up board? The way I see it yes, but I wanted to make sure. Those that are driving 5 of these LDD's on 1 board, are you getting a 48v 8 amp power supply for each set of 5 and calling it good? I'm looking at a 36v 9.7 amp unit. Should provide some overhead and not have to run at 100%, right?

The board, especially the 5 up, they take 1 PWM per LDD, correct? Obviously the goal here is to have 5 dimmable channels for me to adjust.

TIA for all the development on all this stuff!
