I've got a SMPS which I'll be supplying with 230Vac. It outputs 24Vdc. Maximum power output is 600W. The efficiency is 89%.
I know that on the DC side, I'll be drawing 240W, or 10A. How can I work out the AC power draw?
Also, what cable size should I be looking at if I wanted to draw the full 600W from the PSU? On the input side, I would have thought 2.5mm^2 is ok, but surely not for the DC side with over 20A.
