Unit 1/10 kW for 230-V sensor
1 kW for 3.25/√3 sensor, for 100/√3 sensor, and for 400/√3 sensor
Range -32768 to 32767
For example, Modbus value is:
1000 = 100 kW for 230-V sensor
1000 = 1000 kW for 3.25/√3 sensor, for 100/√3 sensor, and for 400/√3 sensor

NOTE
The active power in 3 phase (register address 1042) will saturate after 32767.
3-Phase Reactive Power
(Address 1043) This register contains the 3-phase reactive power.
