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

[reefinnewb]

Looking to possibly expand my lighting from 2 to 3 or 4 lumia 5.2. I have one of the boards and it works awesome, however since we can no longer get them, how would I expand the board to allow an additional set of drivers? Since everything is integrated, I'm not sure how to seperate the output from the board. For example, use the controller board for one set, then expand to a coralux board for the other LED pucks. How would I break the bluefish outputs out?

It should be possible to use the CAT5/6 output from the board to pass the PWM signals to the Coralux board.

Ethernet CAT5/6 cable is used to interconnect the boards. Each board now includes a 5v buffer on each of the 6 PWM signal channels, making it possible to daisy chain dozens of boards off one BF Mini.

I use pin # 1 & 8 of the Ethernet cable to pass a common ground connection, and pins 2 - 7 to pass the 6 +PWM signals.

Perfect!! Thanks for that. My next question was going to be about pinouts of the ethernet jack.

Hi,

I cannot access the write-up referred to in the post below. Can someone please re-post it?

Do you know if there are the eagle files for the O2Surplus boards?

Now when Ben is mentioning O2surplus' boards, I thought I would share a little write up I did on what O2surplus made for me:

I may have some boards I need to check

I am interested in one if you have any spares.

Anyone have the overall dimensions and Hole to Hole dimensions of the board? Looking to print an enclosure. Mine is going to be a bear to measure in it's current state. Even if there is an Eagle file with dimensions. Thanks.

Which board? The arduino?

Sorry, yes. With the bluefish controller.

Are the eagle files available?

Here's my latest design. This one uses the WEMOS D1 Mini for WiFi control instead of the BlueFish Mini. It features 8 PWM channels, Dual SCW's, 3 cooling fan connections, ect.. The PcB measures 100mm X 150mm. I've got a batch of 10 coming in the next week or so. I'll post the design files if this design proves sound and defect free.

I'd be interested in this also. I've been looking over the forum trying to find a LDD board with 5-8 slots. Possibly with the 12v add ons. I can't find any of 02surplus design files but, I did find the Rrasco's board page of LDD4 boards. I'd like something with a few more, I'll be using 350w 48v power supply.

I ended up ordering a pair from Steve's LED's. He carries both 4 and 8 slot.

I was wondering if I could get a recommendation for a power supply for my system? I have a total of 204 leds with the following ldds. None of them running at 100%
(9) 1000
(8) 700
(2) 600
(1) 400
(1) 350
I had a used meanwell rsp 1000-48 power supply that died after quite a few years of use. I bought the same as a replacement and it died after 1 month. Dont know if I got a bad unit or it is too small for my system. I would like to hear of a recommendations for either a replacement or another rsp 1000-48. Meanwell also has a se 1000-48 I thought about purchasing.
thanks
jeff

204 Led should fall below 1000w. And even if you run the ldd at 48v your below a 1000w of drivers. Should be fine. Probably a bad unit or overheated.

 

[jjoos99]

Do you mind looking at the meanwell se 1000-48 would be ok it use. The think maybe the rsp 1000-48 has extra bells and whistles I don't need.
Thanks
Jeff

Should be fine. I'll be using multiple lrs 350w 48. They were cheapest wholesale unit I could find. also the 89% efficiency is pretty good. The lower watts have 90 and 91. kinda odd but, it basically means they're using the same size internals. I wish I could afford to use a higher efficiency power supply but, the price goes up very quickly.

i need this, or at least this 8up with a bluefish mini.

I have the 6up but need to find them. Shoukd be easy enough to edit and make 8up

i have a 4up ldd-h & swc 02Surplus board with 2 ldd 1000 and 2 ldd 700 and a scw05c-12 for fan control and a meanwell se-350-48 power supply. i am no longer using..pm if interested.

Does anyone have photos of a finished DIY LED array they've made? I'm curious to see how people encase their DIY lights and protect the electronics.
