With the 48V's you are talking about wiring the stripe in parallel?the usual 48V meanwells arent a bad fit for your 4 feet strips.
at 700mA f.e. you will be in the CC region at 43.7V.
with 8 strips this would be ca. 270W, so may check out a 320W 48V.
if you want to drive them harder then the next bigger one 480W pushing you above 1A each strip, ca. 1.3A, that quite high for non cooling allready btw.
some XLG drivers will be a nice fit for sure and there will be some 700 1500 or 2100B fiting.
a option if you want to save wiring and are ok with the voltage.
as you have 8 you need to stay with a even number, so 2 strips in series as a option, this way you can route the power so your + and - are on one side terminated.
its a bit up to you.
Do you have any opinion on the number of strips to run in series as far as how high the forward voltage starts to climb?yep, as far i see this could make sense.
otherwise decide for how many you want to put in series and say.
its really up to you, depends a bit on your wiring.
I'd keep the forward voltage under 300V. For 700ma this happens at 200ish watts. Or 6 strips. You'll start to have trouble finding wire rated for enough volts amd same thing the connectors on the boards etc are only rated for so much. I've seen both 60V and 300V.Do you have any opinion on the number of strips to run in series as far as how high the forward voltage starts to climb?
what wattage are you aiming for?Do you have any opinion on the number of strips to run in series as far as how high the forward voltage starts to climb?
So is the whole "Thermal runaway" not really a concern with running parallel groups of series wired strips? Or at least we are somewhat protected in groups of 2.could imagine a HLG-320H-C3500AB do the trick.
its max is 91V so we can use 2 in series and this 4 times in parallel with a max of 875mA each strip then.
a 320W driver with 48V do of course work in any case, you just need to wire all strips in parallel.
depends really on you and where you see a benefit for your build.
I was looking a bit at Invertronics also as I have some of their larger drivers on my purchased lights. The product line takes some serious research to understand and it seems most of the drivers can be programmed for different output currents etc. Great features for the professional but a bit overwhelming at first for the simple DIY people.btw. youre right that there arent tons of driver options, basically just the 48V and the above mentioned plus maybe the low voltage xlg 240, maybe one else find more options.
ive thought its more, but well as long there are options.
i just realised that bridgelux is giving voltages for hot and cold.
i went after cold, as you need it anyway to startup the panel, startup volage is always the highest, you cant go lower then this.
when it heats up resistance increase so voltage goes down, but they state 85C as hot, i never ever would reach this on my setup and you will be far below too.
my leds never heat up enough to cause such a big drop.
just be aware you wont get 320W, no big concern to me honestly also at 115V youre most efficient at 80% load, so its perfect.
48V Meanwell Power Suppliesinventronics are very good, but have the drawback that you need their programming box.
also with the release of the AB meanwells and their overall lineup i dont see the sense for us, but would need to compare for each case.
how you power the LDD drivers?
Yes they do.Point being - temperature and humidity being low or out of "ideal range" do not cause nutrient deficiencies with a complete electromagnetic spectrum lighting up the atmosphere![]()
