6.6.49 Active Power 2 (P2AVG) – Page 16, Address 11

Default = 0x00 0000

Instantaneous power is averaged over each low-rate interval (SampleCount samples) to compute active pow-

er (P2AVG).

This is a two's complement value in the range of -1.0

value1.0, with the binary point to the right of the MSB.

6.6.50 RMS Current 2 (I2RMS) – Page 16, Address 12

Default = 0x00 0000

I2RMS 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

value1.0, with the binary point to the left of the MSB.

6.6.51 RMS Voltage 2 (V2RMS) – Page 16, Address 13

Default = 0x00 0000

V2RMS 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

value1.0, with the binary point to the left of the MSB.

6.6.52 Reactive Power 1 (Q1Avg) – Page 16, Address 14

Default = 0x00 0000

Reactive power 1 (Q1AVG) is Q1 averaged over each low-rate interval (SampleCount samples) and corrected

by Q1OFF.

This is a two's complement value in the range of -1.0

value1.0, 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

value1.0, with the binary point to the right of the MSB.
