The CJMCU CS5460A Single-Phase Energy Metering Module is a high-precision power measurement module designed to measure real energy, instantaneous power, RMS voltage, and RMS current in single-phase systems. Based on the CS5460A IC, it supports serial communication, energy-to-pulse conversion, AC/DC calibration, and bidirectional energy measurement. It can interface with suitable shunt or transformer current sensors and voltage-sensing circuits. Ideal for smart energy meters, IoT monitoring, power measurement, solar systems, and industrial applications.
