Paralleling Power Supply Units Made Easy ???
I am considering paralleling a couple of 20a variable adjustable psu's for 40a charging. According to what I have read on the world wide inter-web, it can be done quite easily, provided the following ...

What does setting the 20a do? Is it just the max current limitation, such as my Vector which can be 40 or 20 or 10 or 4 as the max current, or is it some special deal where it will maintain 20a by raising its voltage to prevent tapering?
If it is just a max current limit setting, then it is the same as me using two Vectors (same voltage) both set at 20a, which will act exactly the same as if I used one Vector set at 40a. (except the two Vectors will have a tiny difference in voltage so their amps will be a tiny bit different, but close enough)
Some power supplies have a constant current setting which means the output voltage can assume any voltage level within the specified range while producing a fixed current value.
You are talking about setting a current limit which protects the power supply.
