Hello Regarding ID: 961010
I want to understand more about this product.
1) Does the knob is for changing the output PWM duty from 0-100%?
2) What is the output PWM voltage max?
3) What is the PWM frequency?
4) If I supply 15VDC input the PWM voltage will be 15V? Regards
HM

1) Yes,the knob is for changing the output PWM duty from 0-100%? 2) What is the output PWM voltage max is 15V 3) PWM frequency IS adjustable. 4) If you supply 15VDC input,the PWM voltage changes with current.
