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

Checked his accepted best offers and 16.50 seams to be lowest he will go.

still 16.5c is 1/3 of what i pay here for one in the UK!

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.

Not stupid LOL. I literally stumbled upon that solution by accident, and yet it looks as if the PcB had been designed to go there all along LOL.:dance:

As far as the convertor goes, I hear a little "double sided tape" could be used to mount the convertor directly to the LDD-H PcB. That would make for some very short wires between the two + you could power the convertor off the same 12V+ supply used for the cooling fan.

I was totally going to use the same power source as fans. Also, building a tiny board to adjust the fans and make them temperature sensitive, so they are not always on if they don't need to be. It almost looks like you could slide the PWM board in vertically from the picture, I'll try when I get home.

Not a bad deal. I just bought 200 of them for $50. Considering that Digikey charges $2.17 each. I'm getting nearly 9 for the same money .LoL

Its a scam isn't it!

I'm waiting on parts coming from all around the world so i'm in no rush :-)

Are those connectors ok for the LD-1000H?

The best I could get him down to was $17 US, but I was also buying 5 packets. I'm not sure he will go down to $16.50 but it's worth a try.

Yeh he rejected my offer, upped it to 17, but if he doesnt accept i'll just pay the extra £2 as its nothing!
 
Can anyone tell me why people are opting for the 48v supplys for the LDD-1000-H?

I plan on hooking mine up to 6 LEDS each with 5 Channels which each channel has a forward voltage of Forward DC 31.5V-36V.

Would I be right in thinking that I can use two 600w 36v supplys as I don't plan on running them at 1A, but more like 0.7a per channel.

Ordered all the PCBs (5UPs) and parts just need wait for it all to come. Only thing I havent purchased yet is the LDDs as i'm waiting on quotes back, going to get 100 and build up a few boards for freinds (I need 30 myself + some spares).

Anyone bought any LDD-1000Hs from the alibaba site?

No, I got mine from PowergateLLC. Here's how they arrived:

Of 34 LDD-1000s, only 6 had pins straight enough to fit into a socket without a lot of plier and tweezer work. But I did get them all in, eventually. Still waiting to find out if any of them took too much damage to function.
