So I've always used cc a types and now trying to figure out this cc cv ab type driver. Any advice on how to set it up properly and safely. 2 288 48v boards and a hlg 240h 48bbin parallel. I seen info on a and b but not both. Should I set current and use voltage to adjust and dim with the potentiometer maxed ? Kinda confused on the whole deal. I want to he able to change output smoothly and safely. Any ideas using a wall meter to do this. Thank PH

there should be a point where if you have the potentiometer dialed all the way up, turning the screw on the driver should go to maximum brightness... then off as you turn the screw passed 100 percent. Turn it back about 15-20 percent That’s when you know you’ve got it dialed in, and then you can just use the dimmer knob to make your adjustments. A kill-a-watt meter in the outlet is a big help.

hope this makes sense lol

Lol sort of but there are 2 screws on the driver and a pot. From what I've gathered its better to set the amperage and adjust via voltage but then the potentiometer controls the amps doesn't it ?

Thanks for this! I run AB drivers on three of my 600W kits. Good to know how to do this!

And I have a kw meter, I've just been using the powered dimmers though, and the Voltage and Amperage dials are where they were when I got the kits.
