Introduction

AI Translation

The RN8208G is capable of measuring active power, active energy, RMS voltage, RMS current, and line frequency. It supports fully digital gain, phase, and offset calibration. Active energy pulses are output from the PF pin. SPI/UART interfaces are provided for communication with an external MCU. An internal power supply monitoring circuit ensures reliable operation during power-up and power-down conditions.
