|6-0||PACn_6- PACn_0||R||0||8-bit data conversion result of the auto class power measurement for channel n.
Peak average power calculation result from channel voltage and current data conversion measurements taken during the auto class power measurement window.
The equation defining the auto class power measured is:
PAC= N × PAC_STEP
Where, when assuming 0.200-Ω Rsense resistor is used:
PCSTEP = 0.5 W
The IEEE requires a surplus of power (defined as PAC_MARGIN) to be available over the measured auto class power to allow for component degradation over time. See Table 64 for the relationship between PAC and PAC_MARGIN
