The SM Energy GE3222M is a precision-engineered 3-phase energy monitoring and data logging device based on the ESP32 and Arduino programmable interface. It features the high-performance Atmel ATM90E36 (or ATM90E32) Energy IC, which includes an energy calculator and harmonic calculation capabilities.
Key features include:
Energy IC: Equipped with the Atmel ATM90E36 (or ATM90E32) Energy IC, offering high accuracy in energy calculations and harmonic analysis.
Compliance: Meets the standards IEC62052-11, IEC62053-22, IEC62053-23, ANSI C12.1, and ANSI C12.20 for poly-phase watt-hour and var-hour meters.
Accuracy: Ensures an accuracy of ±0.1% for active energy and ±0.2% for reactive energy across a dynamic range of 6000:1.
Temperature Stability: Features a temperature coefficient of 6 ppm/℃ for the on-chip reference voltage.
Integrated Circuits: Incorporates accurate measurement ASICs, MCU, memory chip, and RS485 communication module.
Harmonic Analysis: Provides Total Harmonic Distortion (THD) and Discrete Fourier Transform (DFT) for harmonic components from 2nd to 32nd order, accessible via SPI registers.
Simultaneous Processing: Processes voltage and current for all phases within the same period.
Event Detection: Capable of detecting events such as voltage sags, phase loss, reverse voltage/current phase sequence, reverse flow, and overcurrent conditions for both calculated and sampled neutral line currents, as well as THD+N over-threshold.
