AAARGH !!!
You used the "M" word !!!
BK Electronics http://www.bkelec.com
did sell some self contained single
channel dimmers but I cant find them on their website.
Control current... a few milliamps normally. You can use an opamp to butter
the output of the capacitor. Many commercial controllers only have a single
d-a converter which they multiplex around the different output channels.
The
analogue voltage for each channel is "stored" on a small
capacitor buffered
by an opamp to provide the higher drive current for the dimmer packs.
Just what is this person doing that needs a simulation of daylight ;-)
