6.6.56 Peak Current 2 (I2PEAK) – Page 0, Address 39

Default = 0x00 0000

Peak current, I2PEAK, contains the value of the instantaneous current 2 sample with the greatest magnitude

detected during the last low-rate interval.

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.

6.6.57 Peak Voltage 2 (V2PEAK) – Page 0, Address 38

Default = 0x00 0000

Peak voltage, V2PEAK, contains the value of the instantaneous voltage 2 sample with the greatest magnitude

detected during the last low-rate interval.

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.

6.6.58 Apparent Power 2 (S2) – Page 16, Address 24

Default = 0x00 0000

Apparent power 2 (S2) is the product of V2RMS and I2RMS or SQRT(P2AVG2 + Q2AVG2).

This is an unsigned value in the range of 0

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

6.6.59 Power Factor 2 (PF2) – Page 16, Address 25

Default = 0x00 0000

Power factor 2 (PF2) is calculated by dividing active power 2 (P2AVG) by apparent power 2 (S2).

The sign is determined by the active power (P2AVG) sign.

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.
