6.6.56 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
value1.0, with the binary point to the right of the MSB.
6.6.57 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
value1.0, 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 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.
6.6.59 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.
