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

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
