      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?
