Hi all,
I need the assistance of the electrical gurus here please.
I've got a few tubs of coles led strings from the 2014 christmas season, they are 3 wire from the MFC and I want to wire them into a 2811DC30 controller.
Here are the pinouts...
Controller:
String:
Label:
I powered the string up and set the controller to steady on ie all lights on solid. I then disconnected the lights, pulled out the multimeter and measured between the pins on the mfc. Here are my findings:
-ve +ve voltage
Pin0 pin1 +30v
Pin0 pin3 +30v
To me, this means that the led strings are common –ve, and that pin0 is the –ve, leaving pin1 and pin3 to be +ve string 1 and string 2. Is this correct?
If so, as the 2811DC30 is a common +ve controller, the voltages would be around the wrong way to control these lights I’d assume. To address this I believe I would need to wire 1 string between 3 channels so that the voltage runs the right way through the strings Eg +ve to +ve on the DC30, then –ve into channels 1,2 or 3, and control only that channel, meaning I could only control up to 10 of these strings on a DC30 board. Does that make sense?
It seems like a waste but this is only to make do until I can order some custom strings next year hopefully.
If I’ve done something completely wrong here I’m more than happy to be corrected. Thanks in advance.
