This signed register contains the power factor of the total power. The power factor is calculated as:
It is expressed in units of 0.00001; thus, unity power factor is expressed as decimal 100,000
(0x00000000000186A0). This register is presented as a two’s complement value, so that a load delivering real power
to the line (that is, reverse power) is seen as having a power factor of -1 (0x0000FFFFFFFE7960).
This signed register contains the real accumulated energy delivered into phase A/B/C or total. The register is calcu-
lated according to the following formula:
This signed register contains the reactive accumulated energy delivered into phase A/B/C or total. The register is
calculated according to the following formula:
This register contains the apparent accumulated energy delivered into phase A/B/C or total. The register is the prod-
uct of the ENR_CC and X.ES registers.
Reactive Energy, Phase A/B/C/T (ENRQ.X) (A: 0x8D1, B: 0x8D2, C: 0x8D4, T: 0x8D7)
Apparent Energy, Phase A/B/C/T (ENRS.X) (A: 0x871, B: 0x872, C: 0x874, T: 0x877)
Real Energy, Phase A/B/C/T (ENRP.X) (A: 0x8C1, B: 0x8C2, C: 0x8C4, T: 0x8C7)
Low-Power, Multifunction, Polyphase AFE
