Range -32768 to 32767
For example, Modbus value is:
1000 = 100 kVAr for 230-V sensor
1000 = 1000 kVAr for 3.25/√3 sensor, for 100/√3 sensor, and for 400/√3 sensor
NOTE
The reactive power in phase 1 (register address 1024) will saturate after 32767.
Power Factor Phase 1 (Cos φ )
(Address 1025) This register contains the power factor phase 1 (cos φ) in 1/1000.
