This document is about STEVAL-IPE006V2 high end meter demonstration board. The demonstration board has active, reactive, apparent, fundamental active energy, VRMS, IRMS and frequency measurements, neutral wire anti-tampering, meter box tamper detection, time stamp, PFI/PFO: power management, data backup, LCD display, power line communication, automatic meter reading demonstration, SMPS power supply, RS232 IAP, PC interface control, Class 1 application.
The STEVAL-IPE007V1 is an evaluation board designed to develop single-phase power and energy meters. It is based on the ST7FLITE microcontroller and satisfies IEC 61036 accuracy requirements for Class 1 meters. The board measures active power, voltage, current, power factor, and line frequency in a single-phase distribution environment.
The board measures active power, voltage, current, power factor, and line frequency, and it also displays the current date and time.
The board uses two current transformers to measure active power in both the live and neutral wires to detect tampering.
The ST7FLite20 microcontroller performs all the measurements in the meter.
