Best option for auto-dimming Meanwell 48D?

I finally finished building and planting my DIY extravaganza tank (see more info here). So now I need a new project.

I'd like to automate the dimming cycles on my Meanwell 48D drivers (which have a 0-10v control input). I see that I can spend $~200 for a Reefkeeper Lite with a lighting control module, but are there other options? I would be happy to DIY this too, but I have no idea how to design such a thing--I could only build it. BTW, I'd like to control 3 drivers separately--is that possible with the reefkeeper?

0-10V is tough...

I assume your running 3W cree's and u have 3 in serial so you get 9V output on them?

Or you have 4 of them in serial that your just running downvolted at 10V?


The thing about dimmers is you need to match the voltage range for the circuit you have.

A Dimmer which can only go down to 9V-24V wont work in your scenario which eliminates a lot of home automation products which are based off MIR25 transformer..

Maybe some might work with a lower range.. from 3V-12V..... look up home automation and u can probably use what they use on the MIR25's .


Ummm im playing with manual pots/rheobuses... 12V tho... not 10V.
Something which u normally see in computer cases and not outside on top of a fish tank. :P


^ if u need some advice on something like that DIY, i can probably help you convert a PC system's electrical to a working LED array.
However that meanwell needs to do 12V for the PC accessories to work.

This thing will do it. It can also drive a few smaller LED arrays all by itself, but it will dim a Meanwell just fine. $80 and some soldering, not bad.
