help wiring scheme for dimmable LED lights

I need some help with my wiring scheme. Does this look like it'll work or am i missing something.

So far it looks like i need to get a


Mean Well ELN-60-48P dimmable driver

10K Ohm Linear Potentiometer

some type of 10V dc power supply

Ammeters

anything else?

I think the wiring diagram is ok. But I don't think the "P" version of that meanwell driver will work with an analog dimming circuit. You'll need the "D" version for that. I know there's been "talk" of some interchangeability issues between the two models, and that one of the two has a lower cut-off point than the other.

The "P" model can use an analog input, but it's not very smooth or linear. It really should be used with a controller, or some other pwm source. The "D" model is much better suited for analog control.

how do people set up programs on their LED's so that they change their dimming throughout the day? for example, their tank starts out dim and gets brighter as the day progresses.

Some computer programming knowledge will come in handy with this one

Since it's hard to find 10v power adapter you can use two potentiometers instead of one as shown here (discard transistor and arduino part) and regular 12v "wall wart" adapter:

rapid led has some 10 volt adaptors that are pretty cheep so i think i'll just go with that. However that wire scheme looks good. The only thing that i want to add to that diagram is an ammeter to measure the current change as i adjust the pot.
