Low-Power, Multifunction, Polyphase AFE
with Harmonics and Tamper Detect
This register contains the apparent instantaneous power delivered into phase A/B/C or total. Power is calculated
from the instantaneous energy measurement according to the following equation:
The register is 8 bytes long, but the most significant 2 bytes are not used. See the PWR_CC register description for
more details.
This register contains the RMS voltage on phase A/B/C. The units are defined by the VOLT_CC setting such that V.X
= X.VRMS x VOLT_CC. In this equation, VOLT_CC is the conversion coefficient. See the VOLT_CC register for more
information.
This register contains the RMS current on phase A/B/C or the neutral channel. The units are defined by the AMP_CC
setting such that I.X = X.IRMS x AMP_CC. In this equation, AMP_CC is the conversion coefficient. See the AMP_CC
register for more information.
