I see several topics about Chinese board TB6560.

But still not clear to me that occurs with top voltage (36V)

1.- 36VDC exactly happens?

2.- Then what is the maximum voltage to work fine?

3.- If the maximun voltage to 7812 and 7805 is 35V,
THEN exactly 35VDC is the maximum voltage to work fine???
ELSE 34.9V es the maximum voltage to work fine???

4.- In your experience what voltage you apply?

I appreciate any related information.
