Hello!
How many volts should I drive a MeanWell 320H-48A with 12x Samsung FB64B in parallel?
46? 46.5? 45.5?
Thanks in advance!
Driver Voltage
I doubt you’ll even be able to hit 46V with 12 of those strips on a 320. Your driver will go C.C. mode before it can hit that voltage. Just crank that thing wide open!

Didnt know it could go on CC mode. Where should I set the voltage at? I'm confused about this topic.

If you have time, watch my HLG Series Part 2 video. It’s second from the top on the blog homepage right now. That’ll explain constant voltage + constant current. It’s a long video but should clear everything up.

You’ll notice all the constant voltage meanwell hlg drivers are actually CV+CC drivers. They’re CV drivers until they hit their max, and that acts as a ceiling and thus limits current instead of votage. So wherever you set the voltage so that your strips draw more current than your driver can provide, that is where the driver goes into CC mode.
Yup. You can also set this C.C. threshold by adjusting the current pot down on an A type or B type driver.Ted wrote: ↑Mon Jan 01, 2018 8:46 pmYou’ll notice all the constant voltage meanwell hlg drivers are actually CV+CC drivers.

Thanks. That video helped understanding how it works. I will post some feedback as soon as I start doing more tests.LEDG wrote: ↑Mon Jan 01, 2018 10:16 pmYup.

I managed to do another testing to my circuit today. At 45.32V the circuit is pulling about 6.5A (measure taken after 5min).LEDG wrote: ↑Mon Jan 01, 2018 10:16 pmYup.

Should I pull more or I leave it as it is? Driver is rated at 6.7A.
Thanks in advance!
