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 ...

That's true.
However, same goes for CC mode. The voltage is always in a defined state.
When the PS is connected to the battery, the PS's voltage is Vbat + Vcable.
When the PS is disconnected from the battery while in CC mode it immediately switches to CV mode. The voltage goes up to the defined regulated set point. There's no hocus pocus. Nothing gets damaged.ken white wrote:Salvo wrote:
...BTW, I see no scenario where the power supply is damaged when removing it under power from the battery. When in CV mode, the PS voltage will remain at the exact voltage level when it's unloaded. The voltage doesn't change whether it's loaded or unloaded...
I don't think anyone besides you stated this...
That is only true if using a current limited CV supply and not a true CC supply.
My concern is that if the battery is disconnected, the CC supply could raise the supply voltage to the main DC supply and some input ports could become damaged.
Just a precautionary note...
