Pmean2

N Line Mean Active Power

Qmean2

N Line Mean Reactive Power

Address: 6AH

Type: Read

Default Value: 0000H

Bit

Description

15 - 0

Pmean2[15:0]

N line mean active power.

Complement, MSB is the sign bit. Data format is XX.XXX, which corresponds to -32.768~+32.767kW.

If current is specially handled by MCU, the power of the 90E21/22/23/24 and the actual power have the same multiple relation-

ship as the current.
