Meanwell LDD driver: for those who want to dim to 0 using Arduino

Ok- I went back and tweaked the designs a bit by isolating the SCW05's output from the ground plane and added a 1206 chip led for a "power indicator". I could not find any information in the data sheet that would suggest a ground connection to the VOut- terminal would be OK, so I played it safe and left it floating.
Here's an image of the PcB. The EAGLE schematic and board files, along with the Gerber files for production at Itead are attached below.

o2 could you add a circuit like this to the ldd + converter board and have the power coming off the converter for just three fans instead of four as in the diagram and also add isolated terminals for two temp probes just to make it easy to hook them up

Let me see if I understand you correctly. You want me to ditch the 3 pin fan connector & screw header on of my design, and replace it with the control circuit that you've posted? And make it for 3 fans instead of 4? Do you care if I use SMD components? What kind of connector would you like for passing the control signals and ground to the Arduino?
