Led driver replacement

Hello

I'm looking for 2 led drivers for the SB350SB
http://www.ledflowergrowlights.eu/growlights/SB350SB-Pro.html

My 2 outer rays are not working anymore.
When i switch drivers they work so it must be the 2drivers fault.

I wonder which drivers i will need and where i could buy them
On the black boxes they have written C100 7030-c
When i open the drivers they have written this :
HOYETY 0529
PQ3220 24-36

I have really searched alot but it seems they made it very hard to find it out.

Thanks in advance

Can you post a picture?

Can you measure volts and current from the drivers that are still working?

You can probably not find those drivers but you might find something with equivalent specs.

Or give us a diode count of the string not lit by the driver, then we could at least guess what chips they are using as I see no reference on the chips used from their specs.

Was a bit to fast opening this thread.
Found an eletronic expert in my city where i will pass by this evening.

I have 12 rows with 24 leds in each row so 288 leds.
On the led it says 362w so that must mean 1.25w/ led
Altough there are red and blue leds so i don't know if there could be a difference.
Meaning about 288/6 boxes = 60Watts trough each box
And working on 230V

Well i brought the 2broken ones to someone today.
He indeed asked to measure out the voltage on a working one but i couldn't get it working.
Was fluctuating to much (3V to 47V)

I think the written numbers on my boxes are : Cu7030 instead of what i mentioned.
Anyway , tried to google that too but couldn't find it.

Ok, that won't help. I'm going to guess that by the time you play about trying to sort out the driver that it will be cheaper for you to buy another cheap light

exactly what i thought.
Well it wasn't that cheap altough i bought it used.
It was new a very pricey led (in the years)
Well i learned my lesson and will only buy new ones from now.
Thanks for the effort.

Click to expand...
So it has 6 drivers powering the 288 diodes? Is it Dimable?
So just as a guess, I'd say your looking at a driver that's around 85 volts at 700 mA which would give you 59.5 watts from the driver. That's just a guess but that's around what the old Chinese drivers drivers used to conform too.

Here's a similar type driver

If you cant find an alternative driver just rewire the strings that are out to the working drivers and use it as supplemental light or veg light.

Its not dimmable
And yes 6 drivers for the 288 leds
It has 2 switches tough -> for veg & bloom mode
I'll try again in some minutes to measure the voltage on another way to make it sure.
Didn't got an answer yet from the guy i gave them too.

How should i rewire it ? Because i'm running another grow and to be honest i'll need this led..
Could i wire 2 led rows to one box ?
Or can i just run it like this :
Connect all 4working drivers to the 4 rows with veg status and leave the other ones open ? ( not sure if i won't damage it then)

Lol the electrician said it would be 72€ to fix one power converter lol.
I am googling but it seems hard to find an old converter like the ones you said

Update;

nvm , tried power supply as keyword and this one popped up
