Driver for 3x Vero29 Gen7 type B?

Hey,

Can someone help me with which driver to choose for 3x Vero29 Gen7 type B (1.8A @ 52V)

HLG-320H-C2100 is rated for 76-152V (154V max) and 2.1A
3x COB's wired in series @ 52V each = 156V

Will this overload the driver at 156volts?
I see overload protection @ 160-175V

What will this driver actually run these COB's at?
I am assuming only approx 51.3V each?

If so will the COBs handle being ran at 51.3V?
Will current be limited to approx 1600mA? (at 51.3V?)

Or would a HLG-320H-54 be better for this?

3x COBS wired in parallel

This would allow it to run at 1.983Amps max per COB
At this amperage, the COB will pull about 53V each I think?

This seems alot better. Is there any reason to go the 1st route?

I read that some Veros are not within close enough voltage to be ran in parallel?
I think the Gen 7 series fixed this problem correct?

I've made a few 3 cob Vero 29D panels using BXRC-30E10K0-D-73 which is the 37.6v version and Match it with a HLG-240h-C2100B and they work great. You can also step it up to 4x 38v cobs and run it with the 320h-c2100b which is how I make my panels now. 2 panels per 4x4 and getting amazing results!

You should look into the HLG-320H-C1750B (183v max) if you already have the chips and are stuck on running the 320w version with 52v chips. I wouldn't personally run the 52v chip @ 2.1 amps as your going to start losing efficiency.

I have made plans on how to make my 4 cob panels with 4 vero 29D's with 320h-c2100 and have made 20+ of them. Feel free to contact me if you are curious on how I build mine and maybe I can help you out...
