Hey all I have been searching for a already-built solution that would output 3.3vdc, 5vdc and 12vdc @ 5a. I have found that here:

However the issue is that I will be feeding this 48vdc (POE) and it seems that the max this thing can take in is 40v.
Do you think it will be fine with 48v? Is there anything I could add to the board so that it can take up to 50v?

Thanks! Good call, I use these to buck/boost power to use 'not quite to spec' or 'oriental/asian/european 'wall-wart' power supplies for my small 3 - 24v devices too.
