It looks like it just provides 0-10V signal to the power supply and doesn't alter the current to the boards directly.

I think a simple 100k ohm potentiometer set up would be better for this application.

They look genuine to me, they are made in China so they probably get a good deal and potentially fewer people to add their bit of profit on before you get it. I've put the serial numbers in here and they came up ok. http://www.meanwell.com/serviceReport.aspx I've searched for fake meanwell drivers a...

The set up will probably max out at 270watts depends how much current the driver will allow, the A type drivers will normally do a little more than the specs suggest.

An HLG-320H-C2100A or B would be a better choice.

The max voltage of that driver is 119V so wouldn't run 2 boards in series, instead the current is split between 2 boards wired in parallel The maximum current of these boards is 1200ma, so if the driver which is constant current, is set higher than this and one board becomes disconnected it would ov...

Probably just a failed chip.

You need to give more information on the wiring, power supply and dimmer, but I doubt you have done anything wrong of it's been fine for 2 weeks.

Have you contacted the supplier? Which one was it? Got a link?

If you adjust the current potentiometer on the driver to give a maximum of 6A it will reduce the voltage to whatever it needs to be to maintain 6A but only to a minimum of 24V as in the specs. Assuming there are 20 560mm EB Gen2 strips arranged in 10 pairs of series wired strips in parallel each pai...

The constant current region for that driver is 24-48v it would work by running pairs of strips in series and turning down the current potentiometer but if one of the strips goes out for any reason the current would be shared between the remaining series wired pairs probably overpowering them.

Your set up looks like its bending the boards, which probably won't do them much good. If you moved the mounting points about 4" from each end it would improve but overall I think some 3/4" or 1" angle down each side would be better.

The figures don't add up, at 142v the multimeter should be reading over 2 amps, or at 1.67 amps the multimeter should be reading less than 142 volts. I'm guessing the multimeter isn't giving accurate readings. If the readings are accurate, which I'm sure they are not, you are still getting 234watts,...

4 QB120 or QB132 looks like a much better deal unless these chips are something special, the site lists QB's as lasting 50000 hours which is over 7 years at 18 hours a day, lasting 38 years longer than that isn't a selling point as I'm sure current LEDs will be obsolete by them. Can anyone explain w...
