FYI that's a PWM driver, not 0-10v dimming. So you can supply it with 10v to get 100% but you can't dim it by lowering voltage. You probably should have bought the D version, not the P.

I have no idea where to get the actual dimmer.

You'll have to get a dimmer built out of a controller for PWM dimming. It doesn't function with analog dials/potentometers.

As sphelps mentioned, you may want to pick up the Meanwell 60-48D, which is the analog dimming unit that can be manually dimmed through a potentometer.

yea probably next built, but for now ill just attach a 10v adapter without dimming functions. Or built one. But atleast it brights and shine pretty on my corals XD.
