FAQ: can use one output wires for this 12v 300w led drivers?
There are 2 output wires for our standard 12v 300w led drivers, if one output wire is necessary, there are 2 solutions we can provide:
1) . Change the AWG of dc cords from 18AWG to be 14AWG.
2). Still using standard 2 output wires drivers, but connect the polarity of “+” with “+” and “-” with “-” of this 2 wires as one output wires.
Any questions, contact us for more evaluation.
