STEVAL-IPE007V1: Single-phase energy meter

with tamper detection based on ST7lite2x

Introduction

This 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 I

b

=10A and I

max

=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

 an
