STEVAL-IPE012V2: single-phase energy meter with 80 A maximum
current based on the STPM10 metering IC and STM8L152C6 MCU
Introduction
This document describes the functions of a single-phase energy meter based on the
STPM10 metering IC and STM8L152C6 microcontroller. The demonstration board solution
is a fully functional single-phase solution with parameter display, tamper management,
maximum demand (MD) calculation, EEPROM data logging and low-power management.
The meter specifications are:
■ Accuracy: class 1 with dynamic range 200:1
■ Nominal voltage: 240 V
■ Nominal current: 10 A (ITYP)
■ Maximum current: 80 A (I_MAX)
■ Operating range: 0.6 Vb to 1.2 Vb
■ Meter constant: 1600 impulses/KWh
■ Power frequency range: 45 Hz to 65 Hz
■ Sensor: primary side CT and secondary side shunt
■ Communication interface: IrDA
