There was comment from salmonetin, but then he deleted it. He provided several links. One of them gave me solution for the first issue - just add 100k resistor between DIM+ and DIM-. So, the first problem is solved. Thank you, salmonetin :)
Anyway, second problem is still here. Is it only my...
Hi guys.
I have XLG-240-M-AB and trying to control dimming using PWM. I noticed following:
1. If DIM+ and DIM- are not connected then voltage between them is 14.5V, not 10V as specified in many sources.
2. When I connect 96 kOhm resistor, voltage on it is 9.33V
I'm using Arduino's PWM (500 Hz)...
