Driver for 2 Cob 50w each (100w)

[Volkgz]

it will work?

ELG-100-C1400A




for 2 cob (clu04h-40/85-prb) in serie

Didn't realise citizen had come up with some hort cobs.

But that cob is only red and blue. Is it for supplemental light or main source of light?

@CobKits would know more.

Just looking at the chart on page 5 of data sheet "forward current vs forward voltage"
I don't think it would work. looks like about 37v or just less @ 1400mA which would give you 51.8w per cob and put you over the drivers capacity voltage and wattage wise.

Would still like a second opinion though.

I'm thinking it will most likely work.

 

[CobKits]

a gamble but my bet is that it would light em up, possibly at a sligthly reduced current

but with 1400mA its consumption and current would decrease considerably due to the temperature, right?



ELG-150-C1400A or ELG-150-C1750A can work better?

hlg120 is prob same price as elg150

 

[Volkgz]

hlg120 is prob same price as elg150

it's around 10 $ more expensive in my country
elg 150 its good then for 2 cob (50w-100w) ? or should i going for hlg 120 c1400a

 

[Airwalker16]

150-1750 definitely can not do it. @CobKits are the ELGs only for 220-240v houses?

reason?

 

[Volkgz]

Any recommendation then? i would need an adjustable driver from 700 ma to 1400 ma with the integrated potentiometer (A serie) for 2 cob 50w each (50w - 100w)

Isnt that a clu048 though not the horticulture cob you listed first?

I was just going on the data sheet of the part you listed, seemed over both voltage and wattage of the data sheet for the driver. . But you could dim it to reduce both.

Hi Corey, thanks for answering

clu048 3000k cri90 the consumption is almost identical to the clu04h PRB 45/85w, LEDs when heated reduce their voltage and wattage

Then what driver would you recommend to buy?

avaialble current derates with 110V input, see datasheet

master can you give me a hand?

ELG-100-C1400A
ELG-150-C1400A
HLG-120-C1400A

or some other recommendation?

 

[CobKits]

i dont stock any of those, best to look at the datasheets

hlg-120h-c1400 would prob be my go-to out of those 3 (most people use B models for constant currents though)
