IC STPM33 is possible to use for measurement: active power, apparent power, RMS value of current and RMS value of voltage. The question: does it measure the RMS value of current in the case, when AC current is not sinusoidal.

The voltage is sinusoidal but the current is after PWM modulation ( dimming of LED lamp)
