UM0221User manual

STEVAL-IPE007V1: Single-phase energy meterwith tamper detection based on ST7lite2x

IntroductionThis user manual provides a description of a single chip energy meter, STEVAL-IPE007V1, with tamper detection. The meter fulfills IEC 61036:1996 + A1:2000 static meter requirements for active energy (classes 1 and 2) with Ib=10A and Imax=50A. It detects signals from a few mA, and continues to measure accurately even under tamper conditions.

The bill of materials and board schematics are also provided in Appendix A and Appendix B.

Figure 2. Connection diagram of meter

The AC supply is connected to the power supply section of the energy meter. The power LED glows when the supply is on.

There are two current transformers to measure current in phase and neutral wires respectively.

The LCD module provides information about the kWh energy consumed, the input supply voltage, the input current, the power factor as well as the current date and time.

The tamper LED glows if the meter is tampered.

Finally, there is a pulse count LED which glows with a frequency proportional to the measured power. The proportionality constant can be set by the user.
