Single-phase energy meter with 80 A maximum current based on STPM10
metering IC and STM8L152C6 MCU with dual interface EEPROM
Introduction
This document describes the functioning of a single-phase energy meter based on the
STPM10 metering IC and STM8L152C6 microcontroller.
The demonstration board STEVAL-IPE020V1 is a fully functional single-phase solution with
parameter display, tamper management, maximum demand (MD) calculation, with dual
interface (RF and I2C interface) 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 (I_TYP)
■ 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
