6.6.49 Active Power 2 (P2
AVG
) – Page 16, Address 11
Default = 0x00 0000
Instantaneous power is averaged over each low-rate interval (SampleCount samples) to compute active pow-
er (P2
AVG
).
This is a two's complement value in the range of -1.0
value1.0, with the binary point to the right of the MSB.
6.6.50 RMS Current 2 (I2
RMS
) – Page 16, Address 12
Default = 0x00 0000
I2
RMS
contains the root mean square (RMS) value of I2, calculated during each low-rate interval.
This is an unsigned value in the range of 0
value1.0, with the binary point to the left of the MSB.
6.6.51 RMS Voltage 2 (V2
RMS
) – Page 16, Address 13
Default = 0x00 0000
V2
RMS
contains the root mean square (RMS) value of V2, calculated during each low-rate interval.
This is an unsigned value in the range of 0
value1.0, with the binary point to the left of the MSB.
6.6.52 Reactive Power 1 (Q1
Avg
) – Page 16, Address 14
Default = 0x00 0000
Reactive power 1 (Q1
AVG
) is Q1 averaged over each low-rate interval (SampleCount samples) and corrected
by Q1
OFF
.
This is a two's complement value in the range of -1.0
value1.0, with the binary point to the right of the MSB.
6.6.53 Instantaneous Quadrature Power 1 (Q1) – Page 16, Address 15
Default = 0x00 0000
Instantaneous quadrature power, Q1, the product of V1 shifted 90 degrees and I1.
This is a two's complement value in the range of -1.0
value1.0, with the binary point to the right of the MSB.
