That driver runs the boards in a parallel circuit @48vdc at a max of 12.5A current. They provide 2 output leads because the output amperage should be split on the two leads so it doesn't overload a single conductor. You should connect 2 of the boards to each lead. The + lead is connected to the + input of each board and the - lead is connected to the - input of each board.have a Meanwell HLG-600H-48A driver I'm trying to hook up to.4 QB288 boards. They have an extra lead I have no idea what to do with and can't get it working. Please help. I will post pics. The drivers I've used before only have one positive and negative lead but this driver has two.
