Hey everyone, First time posting here.
I am creating a lighting system for a vivarium and want the leds to fade in and out during the day.
I bought 5 of these
http://www.ebay.com.au/itm/18W-CBUS-SAA-DIMMABLE-700mA-LED-DRIVER-CONSTANT-CURRENT-POWER-SUPPLY-TRANSFORMER-/131143548831?pt=LH_DefaultDomain_15&var=&hash=item1e88c3bf9fThe dimming part says 0-10v so i created a programmable 0-10v supply using an op amp and an at tiny.
It can output the voltage i want.... but it doesn't seem to work on the drivers.
I WORKED OUT WHY... the 0-10v is the amount running through these pins that need to be dimmed (ACTUAL VOTAGE IS 11.6)... so i wasted a lot of time and effort already.
It mentions leading edge and trailing edge dimmers, so now i am starting to think its not a 0-10v dimmer and instead requires one of those types of dimmers instead.
I am kind of stuck, as i went through a lot of work to make the Positive/Negative power supply and the OPamp and tiny stuff. and now i realise it was all wasted effort.
NOW TO MY QUESTIONS.
Is there a way to make a programmable dimmer that will work with this? If you can give any advice, info, schematics, anything it would be great. i learn fast and am willing to make any circuits i need.
