Energy Units Conversion Coefficient (ENR_CC) (0x01A)

This register contains the value by which the raw accumulated energy value in each phase is multiplied before being

presented to the virtual energy registers. The table below lists the raw energy accumulators and the corresponding

virtual registers.

These registers represent the algebraic sum of the positive and reverse energy in the two “raw” registers noted. Thus, the energy

returned in these virtual registers represents the net energy.
