Hard to find a spec sheet on it. I did for the SV-100-36 so hopefully we can extrapolate from that. Do you have spec sheets for the QB boards you want to run?
Havent looked at any boards specific, was thinking something pre assembled on frame/board with 3000k with red/iv/uv
Thinking something like this? Say 5A 40-48v and driver 5.26A 38V
Or getting 2x 100w CREE COBs
Bridgelux vero29 gen7 3500K 38v COB led chip

Okay, lets see what the specs say. . .
It's wicked close, maybe a bit over what the boards are rated for. I cannot find whether it a constant voltage or constant current. Two boards wired in parallel would give 38v and 2850mA so you can see both numbers are over spec. You would need a big heatsink for those if you did it this way.
BTW, I have two of something similar from the same brand. But they were rated for 38-48v at 2500mA

What is most optimal voltage on board for my driver? Thanks for fast reply!
Says this is rated for 300v. It's a V4 with on/off switch on board they also have free shipping. Get a long 320W heathsink

Morning,
Sorry, didn’t forget you, just suddenly busy. It’s the weekend now so let’s see what we can see here. I see those boards, qb288 clones. I’d buy the real thing from HLG if I was going to get those. They sell it with a heat sink for $30.00 more and it’s the real thing. Anywho. . . Still wondering about constant current VS constant voltage I think I recall it’s constant voltage. If so the qb288 is a contender. I THINK!! Hers some literature that I’m going to re-read.
