Hello there,
I got 4 horticulture lighting group 288 v2 boards. Now I have this driver check out attached picture. Will this work. This was used for big display light. I will get a professional electrition to hook this up with volume control and also breaker/fuse to products leds if anything goes wrong. I just want to avoid spending 150 dollars on driver if this can work. Can this work? if yes, should i use parallel or series wiring?

Happy Fryday!
Parallel the four 288 boards on the 48VDC output. Each board will run at near 100 Watts each.
Do you have 220-240 VAC available in your shop to power that beast. That's what you need.

Jesus Christ 30.2a at 48v. That thing has a 1500W OUTPUT!! I've never seen such a huge driver. It's input is 200-240V so if you're not in EU then you have to use it on 220V power.

I'm pretty sure even if he is on 220, that driver will distribute all 30.2a to the 4 boards, pushing 375w through each one, completely frying them. Unless it's able to constant current mode.

Yes, it can work with parallel wiring. It will not fry the boards unless the voltage is well over 48v. The power draw will depend on the exact voltage from the supply.

From the HLG web site.

VDC Current (mA) Watts at Board
45.72 500 22.86
46.98 1050 49.33
47.70 1400 66.78
48.96 2100 102.82
49.50 2400 118.80
49.86 2800 139.60

It appears to me that each board should draw around 75 watts at 48v. Unfortunately, the picture only shows voltage/current, we need a part number to find more info.

The "volume control" mentioned is known as a potentiometer or pot, it can only be used if the driver has the option of dimming with an external pot.

Thats my thought too.

And yes my region is 220.
And i think this will fry my leds. But electrician is convinced it will make it work. I just dont want to risk it for and expensive exercise.

I suspect that is not a LED driver but a regular switching PS for computers/servers. Get some DC-DC current-limiting bucks and you're golden.

@luckyjack, can you tell us the model number? I see DP something something A, is it the DPS-1500AB?

@Airwalker16 Delta makes a 17.4KWatt 48V driver, 360A. Got 500 square feet of flower space? :)

Ok updated image. This is other one. Taken off from server.
Now electrician says. LED will take what's needed. Not all 30amps will be provided. I will hook up 4 boards parallel.
but im just too nervous he showed me one cheap Chinese led which had like 2amp maximum working with this supply.
Mind you this supply will cost me like 10 dollars so thats why i am going through all this. Already used my cash on 4 boards and 2 double slate 2 boards.

What you guys suggest now. Have a look at the image its much clear.

This leads me to believe it does have a CC mode, if it didn't fry that 2A max diode, or array or whatever it was.
Octopart has no listing for that model # , cant find a data sheet anywhere quickly.... but I did find one for sale retail for $255 USD....
That is one big, bad ass MOFO of a driver....
If I had it, I'd have no choice but to sack up, grab my balls, and hook up everything I thought would fit on it, and run it.....
But that's just me, known gambling fool.....

Also worth mentioning, everything I know about LED drivers has been learned in the last two years, so....Im no "expert"

Went to electrician so here is the example.
its a array of 24v bars two connected in series to make it 48. Each led is 3v.
hooked to that 1500watts supply. It works and everything is fine.

then i hooked boards and controlled the volts from the screw which was inside the supply. I will get it moved outside and hook all the board in a parallel configuration.

But i still don't understand the theoretical side. Anyway what i understand is have the right voltage and led will take the amps what are needed. But drivers like hlg 600 54b which has 11.2 amps i always read that if we hook led they must not go above their maximum. so now whats happening....i dont get it.

This is a constant voltage driver that pegs the voltage to 48V as precise as possible and keeps it there. It is capable to supply 30A but if the load won't pull the whole 30A it will supply what load demands. By the looks of it 288V2 pulls about 1500mA at 48V and that is what you should expect on the output.

Just because the driver is capable of supplying 30A doesn't mean the connected load will see the whole amperage. If so, that server that used this power supply would end up in smoke. If you got a 600hp car doesn't mean the engine will always run with 600hp
