I'd like to use the STPM34 to measure power delivered on two 120V outlets. One outlet will use Red & Neutral, one outlet will use Black & Neutral. When the 120V outlets are not being used, I will use Red and Black on a 240V outlet.
My question is, if the two channels of the STPM34 are configured to measure both 120V outlets, when I run the circuit in 240V mode, would the measured and reported power/energy of the two channels summed together equal the power/energy of the 240V outlet?
The analog connections to the STPM34 would be as follows:
VP1 -- sense_red (scaled 120V Red)
VN1 -- Neutral
IP1 -- red_I_sense_P (current transformer secondary positive)
IN1 -- red_I_sense_N (current transformer secondary negative)
VP2 -- sense_black (scaled 120V black)
VN2 -- Neutral
IP2 -- black_I_sense_P (current transformer secondary positive)
IN2 -- black_I_sense_N (current transformer secondary negative)
Thanks!
