Hi all. I just swapped my 24V Steve's LED drivers to 48V and Meanwell LDD drivers. I had 7 LED's on each string so I combined matching strings to 14 each. I hooked everything up and have the Meanwell LRS-350-48 power supply set to 48v to start. I can measure 48v going in to each LDD, but 0v coming out of all of them and no lights. I know the LED's are wired correctly and have no shorts, they worked before swapping them out and I retested everything. Any ideas? The wires for the PWM aren't hooked to anything on the other end at the moment to rule that out. I'm lost. Thanks for any ideas!
Here are a couple pics. Hopefully everyone can access them.
