I'm controlling a Meanwell LED driver's dimming function using 0-5V PWM from an Arduino, stepped up to the 0-10V PWM the driver expects.
- '0-5v' is the 5V PWM from the Arduino
- 'VCC' is the 10V 500uA wire from the driver's DIM+
- '0-10v' is the 10V PWM output back to the driver's DIM-
- 'Q1 NPN' is a 2N2222 transistor
I could use some guidance on selecting proper resistor values for R1 and R2, given the function of the circuit and VCC at 10V/500uA. I've been advised that the given values may be inappropriate for such a low-current VCC.
(I recognize that this circuit inverts the PWM signal and have accounted for this software-side.)
Thanks in advance!
