Well I realize an Oscope would be ideal here, Just don't have the cash to drop on that instrument. It's on the list.
Second I realize its not AC, Its a square wave that the duty cycle is varied on hence PWM. The thought of my Fluke maybe seeing it "like" ac even though the voltage never crosses zero was just that, a thought.
My meter can read the 490hz of the pwm pins, granted it doesn't allow me to view the actual waveform.
So, I guess I will simplify my question, I was just trying to give as much info as I could.
LED drivers that are dimmable use either a pwm signal or a analog voltage, I was always under the impression that an analog control signal would be 0-10 volts and a PWM signal would be 5v.
Any idea on to why I am not seeing that with these drivers?
