Yair:

 

Item 4 Max column shows “1,2,3,4”.   This is PSE Type?   In truth, according to Figure 33-14, there is a maximum possible Icon that is Ilim_min.

The minimum Icon is the PSE lowerbound template for continuous current, i.e. after Tcut.

 

In the text, the phrase “normal POWER ON state” seems vaguely defined.    Is this specifically a condition where the PD is operating within its allowed steady-state power budget meaning the PSE is operating at or below the lowerbound template for continuous current ?

 

Specifying Icont-2P-unb MAXIMUMS of 668 mA for Type-3 and 931 mA for Type-4 seems confusing.   A Type-2 PSE today can furnish up to 684 mA continuously (with or without pair-pair unbalance) and meet the template in Figure 33-14.   That is higher than 668 mA, of course.    Again, this may tie back to a PSE operating at or below the lowerbound template – that would represent the constraint in order for 668 mA to be a Type-3 maximum pair set current.

 

Food for thought….

Pete Johnson
