Hello all.
My plan. is to use a GHL profilux aquatic computer to adjust the brightness of a large led array.
simples?
the GHL can adjust a 0v-10v line output according to time and a determinable output.
i.e. at 7 am put 1v on line 1, at 8am make it 2v etc etc.
i can buy PWM dimmable drivers easily. (based on the MBI6651) and nice and cheap from the bay.
i'd like a circuit that outputs a PWM signal that the duty cycle is adjusted by the 0-10v...
the PWM needs to be 5v and 1khz.(max)
i hope someone can help. i have trawled and trawled the web, i can find loads of ccts that will allow dimming via a pot. but i want the 0-10v to do it..
thanks in advance.
