Can you wire two LDD drivers to one output pin on arduino?

Yup, I've got 4 LDD-1000 running off one pwm pin. Just remember to tie your neutrals together on your input sides.

Took a risk and its worked! The ps that i have is very noisy. Looking for 48v ps. Will this works for the LDD drivers?

That HLG is a driver in itself. Look for the Meanwell SE-350-48.

Got the similar one, but pretty noisy.

Hmmm, weird. Mine's not noisy at all. Have you metered it out to confirm the voltage? It may not be putting out what you think.

I did. It is not a Meanwell's brand.

Can some one help me with wire sizes.

PS 48V 350W 7.3A powering two boards.
Each board has 4 (LDD-H1000)
Each LDD-H1000 4 (10W 11V 1A) LEDs

Need to know the wire sizes between power supply to the boards and from board to the LEDS.

Thanks,
Kevin

I was encouraged to go 18 ga min for psu to board and 20 from LDD's to LED's. There's a couple links back a page or 2 when I had a similar question. Check them out.

Got a wee bit done this morning over my coffee. Drilled one of the heatsinks to within about 1/8" of the back of the 3-up stars since they'll be on the longest and probably run the hottest. Then a bit of thermal epoxy dabbed in the hole and plunked a DS 18B20 sensor down in there. I need to find a way to block off this vane a bit to try and make it not so affected by the fan, thinking of just cutting a tight fitting piece of foam or something and gluing it down in there between the sensor and fan.
I'll try and wire a bit of it tomorrow morning.
