Product LinkAwesome. I check the datasheet, theres even lower amp versions all the way down to 100mA/200V. @MedicinalMyA$$ whats the dets on the second driver? Id love myself some pwm dimming, the first one seems like it only does nominal, no dimming
I still get a digikey 404 robot on that link but no worries, with a part nr i can hound that driver to the end of the internet.Product Link
Data Sheet
I tested the links this time lol, If they still don't work you could search LD12W-48-C0125-RD or EPtronics on Digikey.
Really depends on how hard or light you're going to run them.I would like to get some info on how many 2' B-lux Gen.3 EB-HO I can run
on this, see pix. Thanks. View attachment 5310648
Thanks for the reply!Really depends on how hard or light you're going to run them.
The driver voltage is correct, just do the math on the current you're planning.
I didnt see anything labeled ho in that datasheet so i cant help you there unless you have one. The regular 560mm eb strips are good from 700ma a piece to 1400. At 1400ma you could run 8 or so.Thanks for the reply!
I was thinking of 18.5V/210mA. I've have a hard time trying understand the math
with electricity/electronics.
I was given 24 EB's and told I needed this driver. Ordered the driver's, was shipped yesterday and should have next week. 12 Gen.3 HO for Veg. and 12 Gen. 3 Thrive for flowering.
Connecting your strips to the driver in parallel you can put as many strips as you want just make sure theyre all the same strip/voltageThanks for the reply!

Assuming that you haven't touched the built in potentiometer there will be no problem at all with the dimming range, adding more COBs you will see a little drop in the power output as each COB will require less voltage.Hi guys, hope you are all fine!
I have 6 Vero 29se BXRC-35G10K0-B-7X and a XLG-240H-AB Meanwell driver.
I was using 3 cobs with this driver but realized they were getting too hot.
Looking in datasheets I've found that probably will make sense using more cobs to decrease the amps in each one and get a higher efficiency.
Altought, using more cobs will make my dimmering range shorter (I'm using a 100K potentiometer), right? How many cobs do you guys suggest for me to use with that driver, intending to optmize the setup?
(I know that the setup itself is not that good, but I kind of panned things in the past years lol)

Thank you!!!
I've actually touched the built in, I just need to reconfigure it?Assuming that you haven't touched the built in potentiometer there will be no problem at all with the dimming range, adding more COBs you will see a little drop in the power output as each COB will require less voltage.
If you set them all up in parallel it will work, no problem.I've actually touched the built in, I just need to reconfigure it?
If I mount up all 6 cobs with that driver, will it work?
Nice, Rocket! Thank you.If you set them all up in parallel it will work, no problem.
Putting cobs in parallels keeps the voltage the same. Just splits the amperage up. If you wired then in series then you would need a driver capable of producing the additive voltage of each cob in the string.Nice, Rocket! Thank you.
Just for me to understand the idea.... in terms of efficiency, more cobs will always be better, since the voltage is sufficient to them light up? Is that it?
The current, splitting for 6, don't have the chance to be insufficient to light them up?
Got it!! Thanks!!Your COB from the data sheet looks like it takes 52V at 1.8Amps nominal. The XLG 240H AB can do around 4.5a at 52V. Meaning if you run 3 cobs each would be getting 4.5a/3 = 1.5a each.
if you add a 4th COB in parallel with the other 3 the drive current to each COB would be 4.5a/4= 1.125a each.
as far as I know there's no real limit on how low you can go with the amperage. But one thing I did notice with the Samsung calculator is that you can hit a point of such low amperage that it's actually less efficient than driving a little harder. I think at like half the nominal current it's kind of not worth it to run any more LEDs. But I think also it's more of a personal discretion thing where you have to weigh the cost of additional chips vs gain in lumens from driving softer.Got it!! Thanks!!
Just one more question... If I keep adding cobs, the current would be 4,5a/(n cobs). Naturally, sometime the current would decrease to a point insufficient to cobs work, right? How do I discover the minimum current the cob needs to light up decently?
Ideally, should I setup 4, 5 or 6 cobs with this drive?
there is probably no measured data for low amperages, so output is a bit random.But one thing I did notice with the Samsung calculator is that you can hit a point of such low amperage that it's actually less efficient than driving a little harder.
