3V3A wiring
①
When the U1 is selected as the PLL source
Based on 3P3W wiring, the three channels of voltage and current are
summed. The figures above show the state when the load is purely resistive.
②
With an inductive load such as a motor
The effective power of ch1 appears negative because I1 lags U1 by more
than 90
°
. However, the summed data for ch(3) is not related to power
measurement, so wiring can be reversed.
