Abstract:
A system conducts a plurality of cycles on the powered device. Each cycle has a detection phase and a classification phase. A classification voltage is applied to the conductors during each cycle. The system measures a current in the conductors while the classification voltage is applied. The system determines a final class responsive to a plurality of measured currents. The final class utilized to determine an amount of inline power to deliver to the powered device.
