6.6.59 Power Factor 1 (PF1) – Page 16, Address 21

Default = 0x00 0000

Power factor 1 (PF1) is calculated by dividing active power 1 (P1

AVG

) by apparent power 1 (S1).

The sign is determined by the active power (P1

AVG

) 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.

6.6.60 Peak Current 2 (I2

PEAK

) – Page 0, Address 39

Default = 0x00 0000

Peak current, I2

PEAK

, 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.

6.6.61 Peak Voltage 2 (V2

PEAK

) – Page 0, Address 38

Default = 0x00 0000

Peak voltage, V2

PEAK

, 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.

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

Default = 0x00 0000

Apparent power 2 (S2) is the product of V2

RMS

and I2

RMS

or SQRT(P2

AVG

2

+ Q2

AVG

2

).

This is an unsigned value in the range of 0

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

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

Default = 0x00 0000

Power factor 2 (PF2) is calculated by dividing active power 2 (P2

AVG

) by apparent power 2 (S2).

The sign is determined by the active power (P2

AVG

) 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.
