4AO extension and PWM for dimmable LED driver

Postby Havor » Sat Sep 10, 2016 10:46 pm

Hi i have a MeanWell led power supply that can be controlled in 3 ways.

Output constant current level can be adjusted by applying one of the three methodologies between DIM+ and DIM-:
0 ~ 10VDC, or 10V PWM signal or resistance.

Can i use one of the 12 the PWM open collectors from the 4AO to dim the LED PSU, or do i need to use the 0~10V analog signal?

Hello, yes I think it might work.
