• Manufacturer: Maxim Integrated Products, Inc.

The virtual registers are calculated values derived from one or more real registers. They are calculated at the time
they are requested, and thus could involve additional time to return a value. Most virtual registers are 8 bytes in
length and are delivered least significant byte first.
This signed register contains the real 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.
Note that the sign bit is bit 47 for all 8-byte signed virtual registers.
This signed register contains the reactive instantaneous power delivered into phase A/B/C or total. Power is calculat-
ed from the instantaneous energy measurement according to the following equation:
The register is 8 bytes long, but the most signficant 2 bytes are not used. See the PWR_CC register description for
more details.
Reactive Power, Phase X = A/B/C/T (PWRQ.X) (A: 0x811, B: 0x812, C: 0x814, T: 0x817)
Real Power, Phase X = A/B/C/T (PWRP.X) (A: 0x801, B: 0x802, C: 0x804, T: 0x807)
