功能介绍

RN8207G is capable of measuring active power, active electrical energy, effective voltage, effective current, and voltage line frequency.

RN8207G supports all digital gain, phase, and offset correction. The active power pulse is output from the PF pin.

RN8207G provides SPI/UART interfaces for convenient communication with external MCUs.

The internal power monitoring circuit of RN8207G can ensure the reliable operation of the chip during power on and off.
