4AO extension and PWM for dimmable LED driver



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

    @1r4uc702:

    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.
