PWM on my Meanwell Powersupply

Other Hardware General Electronics
1

Hi,

my meanwell (meanwell hlg-150h-12b) power supply has an PWM input. It can also be dimmed using an adjustable resistor or an 1 - 10v power source.

Do you think I can dim it with the PWM output using analogWrite()?

Thanks for your help

regards

The input is 10V, so you'll have to level shift and you'll need 10V regulator I suspect.

The input supports both analog voltage and PWM in the frequency range 100 to 3000 Hz.
In practice its probably a low-pass filtered input, so the PWM becomes a linear signal.
It controls the current limit, not the voltage, note.
