The SM Energy FE102M Energy Monitor has the main features:
ESP32 WROOM 32 -Wireless and Bluetooth ATM90E26 (Energy Monitor) Metering Features:
Metering features are fully in compliance with the requirements of IEC62052-11, IEC62053-21, and IEC62053-23.
Interrupts connected to ESP32 Active Energy pulse interrupt, Reactive Energy pulse interrupt, WarnOut fault interrupt, Voltage/Current Zero Crossing interrupt.
Accuracy of ±0.1% for active energy and ±0.2% for reactive energy over a dynamic range of 6000:1.
The temperature coefficient is 6 ppm/ ℃ (typ.) for on-chip reference voltage. Automatically temperature compensated.
Single-point calibration on each phase over the whole dynamic range for active energy; no calibration is needed for reactive/ apparent energy.
Flexible piece-wise non-linearity compensation: three current (RMS value)-based segments with two programmable thresholds for each phase. Independent gain and phase angle compensation for each segment.
Electrical parameters measurement: less than ±0.5% fiducial error for Vrms, Irms, mean active/ reactive/ apparent power, frequency, power factor, and phase angle.
Active (forward/reverse), reactive (forward/reverse), apparent energy with independent energy registers. • Programmable startup and no-load power thresholds
