Ive got a problem that is driving me crazy and i need some help. I'm trying to finish the last part of my controller but i'm coming up with a problem.
I have the following LED drivers from Meanwell:
LPF 90D 48 Datasheet:http://www.meanwell.com/search/LPF-90D/LPF-90D-spec.pdf
These drivers allow for dimming in the following forms:
I should of gotten the ELN series drivers but at the time i did'nt realise there were different types, so i'm stuck with the LPF series
Here is the background to wait i have tried:
The kit came shipped with 2 pots which allow the dimming for the 2 drivers i have. Both worked fine and dimmed up and down. But i want to control it with my Mega.
I next tried the following circuit, but it would not dim at all:
Controlling + lead:
So next i tried this circuit using the 10v supply to control the - lead:
I then tried the following circuit as the 2 previous would not work. This i could get the drivers to dim but with the Arduino fading from 0-5v i could only get the circuit to output 3.5v-6.5v. If i could get this to do the full 0-10V then i would be set.
I must be missing something simple but i just cant figure it out!!
Your help would be greatly appreciated to finally finish the project!
Thanks in Advance,
