Hi All,

I need some advice on the driver chose to connect 7 led panels 24 wats each in parallel. Each of this panel came with a driver D.C. 280 mA 54-100 v but I want to run all of them parallel using only one driver.
Any hint will be much appreciated!

If the driver is 280 mA, and the panels are 24 watts, that would suggest the voltage is around 85V. 280 mA times 7 is 1960 mA. Lets call it 2A. Total power is 168 W.

So you need a driver that is about 2A output, 160-200W, with output compliance that includes 85V (preferably with a comfortable margin either side of that), and runs on whatever power you have.

A Mean Well ELG-200-C1750 or ELG-200-C2100 would do the job quite nicely, with one not quite able to run the panels at rated current, the other slightly over. Both are adjustable down to about 50%.

I hope I don't have to warn you to be careful. These voltages are potentially lethal.
