EF, is there a difference between that type of pwm dimming and actual PWM dimming of the output current?
I know the Mean Well drivers can be dimmed with resistance, 1-10 analog volts, or 1-10v pwm. It should act the same no matter what way you do it with the built in 3-in-1 dimmer function. It works be telling the driver to reduce output current.
Hard to explain my question but it is important to avoid PWM dimming of the actual output current when it comes to LED. As a side note there is nothing worse than a PWM dimmed headlamp, you will think you are tripping everytime you turn your head lol
Do you mean instead of reducing the current to lets say 700mA from 1400mA with a 100k Ω pot, which give a steady current of 700mA. It dims by cutting the current on/off so that its still 1400mA but flickering really fast. That sounds like what your headlamp is doing, kinda like a shitty refresh rate. I have seen fan speed and 3mm leds controlled like that, Im pretty sure that's not how these drivers work.
The problem I have run into is that the arduino PWM voltage is only 0-5v and I have to build a circuit that will multiply the voltage to make it 0-10v. All of this at the moment its way over my head, more testing is required but I am determined to figure it out and to paraphrase/misquote JFK.
We choose to do these things not because they are easy, but because they are hard and we have nothing else to do.
