DescriptionThe board can be used to develop a single-phase power / energy meter with tamper detection based on ST7FLITE. It measures active power, voltage, single-phase distribution environment and displays these parameters in addition to current date and time. It differs from ordinary single-phase meters because it uses two current transformers (CT) to measure active power in both live and neutral wires. This enables the meter to detect, signal, and continue to measure the active energy consumed reliably even after the meter has been tampered. ST7FLite20 is the microcontroller used to perform all the measurements in the meter. This means there is no ASSP (Application Specific Standard Product) used for energy measurement. The active energy consumed is pulse outputs and the accumulated active energy is displayed on the LCD display module (GDM093).STEVAL-IPE007V1www.st.comBoard schematicSTEVAL-IPE007V12/8 1 Board schematicFigure 1.Block diagramSTEVAL-IPE007V1Board schematic3/8Figure 2.C Features Satisfaction of IEC 61036 Accuracy Requirements for Class 1 MetersCost-Effective: no ASSP used, single ST7F MCU AFE(Analog Front End) operation amplifier switches Resistor divider used as voltage sensorWorks powered from a capacitive power supplyRTC interface using SPI for display date and timerDesign with other ST7 MCU can be re-used easily Tamper detection: detects, signals and continues to measure accurately under tamper condition Software calibration for analog circuit, PC GUI available External EEPROM for reliable storage of parameters readingparameters Embedded software easily upgradeable through ICC connector available on the boardDescriptionThe board can be used to develop a single-phase power / energy meter with tamper detection based on ST7FLITE.
