I want to clarify meaning of POE classes.
For example class 4 is defined in range min 12.95W- max 25.5W.
What really means min 12.95 W. ?
What is sense of declaring minimal power.?
For example our system should power 8-10W in normal case, but also 18 W
in some phases (battery loading).
Of course, we must select class4, but what for us stand 12.95W ?
In my opinion nothing.
My doubt is coming of definition class 0 (0-12.95W) and
also class 3 ( 6.xx W-12.95W). What is sense of definition class 3
when is covered by class 0.
Thank in advance
