First off I am NOT the manufacture nor do I have anything to do with these power supplies. I was talking to the manufacture on aliexpress and I suggested that he make an account on here as BLF has a need for high current power supplies like he offers. He doesn’t speak English perfectly and requested that I help him post a thread.
You may contact user RD tech with any questions : http://budgetlightforum.com/user/20499
His aliexpress store: http://rdtech.aliexpress.com/store/923042
Here is a copy/paste of the message from him:

This is a good deal, I would just spring for the 5015 myself for the extra $3. I love my 3012.
You can see my (uncompensated) review of these here: http://budgetlightforum.com/node/48523
Pics from review:
You will also need a power supply to power these with. For LED testing an old ATX power supply works well unless you want to play with XHP35’s. The ATX power supply will limit you to around 11v max.
If you want the full abilities of the voltage then I am using a cheap “48 volt” power supply from ebay. http://www.ebay.com/itm/131664355579
Mine is adjustable down to around 36v for use with the 3012 (test voltage before you connect it). I am using the 150w version of the ebay power supply but if you plan on pumping a lot of power you can obviously get the 400w version as well, due to the low wattages we use with LED’s I did not see a reason for the higher wattage though.
Out the door you should be under $50 for a power supply that is capable of 50v and 15A.
New version released 10-31-16
For those that want to use an ATX or other simular low voltage power supply this same company just released a new buck/boost version of the power supply module.
It outputs 0-32V and the input is 6-40V with a 5A max current.https://www.aliexpress.com/store/product/RD-DPH3205-Buck-boost-converter...
This really opens the door for more compact and easier to build power supplies if you do not need the higher current and voltage abilities of the DPS5015
It is on sale during the introduction for $28.99 for 3 days, grab it while you can, they always do this when released and the price DOES go up after that.
Email I was sent about this:

Here is the Design for the Acrylic case I made in case anyone wants to make one. It is cut out with a laser cutter from standard hardware store .08” acrylic sheet (“plexiglass”). Thicker acrylic would be stronger but costs a lot more and is much harder to find.
Proper acrylic glue will be stronger and look better but hot glue or super glue works just fine as well.
