MeanWell LDD-1000H led drivers

[foglia]

I would to use MeanWell LDD-1000H led driver, but in datasheed I don't found any information about PMW current requirements.
I need to driver 8 LED drivers wirh Ardunino but I don't kone if this is appropriate for Arduino directly connection. 40mA is the limits for Arduino
Anyone have already tested this drivers ?
Many thanks and regards

Wow, those are impressive drivers. Looks like they're fairly new.

If you're worried, rig one directly to the Arduino and monitor current. I bet it will be very low. If it's too high, just put a transistor in between.

Also I think that are impressive drivers. I will receive these drivers tomorrow. >These drivers have 98% of efficency and very low price. I bought them in Europe at 5,50 € each

Did you manage to get PWM working with these one the Arduino? I can't :/

 

[mr.wilson]

Any updates on the drivers working with arduino?

 

[nbinc]

I connected the LDD-700L drivers to the Arduino PWM.
Everything works, only the brightness gradation of 255 steps.

Hi guys, I have a question for you
What the amount of led I can put on this driver.

Anywhere from 1 to 14 leds per driver using a 48volt power supply

Hmmm, so you could use something like a Meanwell NES-200-48 (48v, 200w max) and then run a handful of these ~$5 drivers off that no problem?

Is there any advantage to those brick drivers (ELN, HLN, etc)? Or is it just the encapsulation of everything?

One power cord powering everything seems way more convenient.


Edit: Or a Meanwell SP-200-48 (didn't realize the NES version doesn't have PFC built in)

I'm powering 7 LDDs with a SP-200-48. I mounted the drivers in my fixture so I have 1 cord to plug in, 1 cable from the power supply to the fixture and 1 data cable from the controller to the fixture. It makes for a very clean setup.

Bravo, I assume they can individually be dimmed? I would think that if you hooked 7 into one power supply with only a V+ and V- slot that you couldn't get separate voltage to each driver.

Nice can you post some picture of you leds set up please.

 

[davilae1]

guys I have a question just finish setting my bow front corner 100gal. how many leds i sure use for this tank?
48 or 60 leds, am planing on using the 4 or 5=LDD-1000H, not sure what power supply, I want a good one bot not to expensive I need to have this leds *** low as possible, my budget is very tide.
Leds I will buy them from rapid led with black heat sink 2= 6" x 20", splash guard and fan.
my other concern is the controller, I will love to have apex mmmm bot is not happening for now, I need other options any advice is very well appreciated.

The tank size is 36" diameter by 25" hi.

What you think about this controller from rapid led
DDC-01 PWM Controller w/ remote control

[sfsuphysics]

I'm not a fan of that rapidled controller at all, it's quite pricy considering it's limitations.

Typhon controller from Boost LED is nice, 4 channels of dimming and upgradable Arduino programming if you have a desire. There are also folks making nice acrylic boxes around for it. Check out the other thread on these drivers here for some nice boards for mounting the drivers and powering them from an NES-350-48 or similar.

 

[davilae1]

for the acrylic boxes np I can built my own, I have a carpentry shop and work with plexy, am looking around for my different options to light my leds and controll them, looks like the typhon is a gd option.

 

[sfsuphysics]

Typhon is what I've been looking at as well, cheaper than the other one mentioned with more control ability it seems. 4 channels vs. 2 of the rapidled one as well. Although only 2 drivers per channel, so if you're making a really large array that would require more drivers per you'd have to buy multiple controllers, or build an amplification circuit of some sort. I seem to recall this was an issue with the Reef Keeper's light control, I think they put an OpAmp circuit on it to allow more than 2 drivers, but I'm not certain (also not sure if the Reef Keeper is PWM or not)

The Reef Keeper ALC is 0-10V. Those little LDD's are pulling that much PWM current you can only put (2) drivers per channel? I have a bunch of the LDD's but no controller yet so I can't measure it.
