产品概述

描述

The STDES-EMETER1PV1 single-phase smart meter is based on STM32L433VCT6 MCU featuring ARM Cortex-M4 core and STPM33 IC for electricity metering with an accuracy of 0.1%.

It measures electric energy consumption over defined time intervals and sends collected data back to the utility for monitoring and billing, also tracking all the tampers, with the correct date and time.

The smart meter meets the most up-to-date smart metering requirements, such as multi-tariff billing, reactive energy measurement and power quality monitoring to enhance generation, distribution, customer service and billing.

The STDES-EMETER1PV1 comes with an expansion connector to provide GPRS/SubGHz connectivity and a relay control which allows remotely connecting/disconnecting the load.

The embedded STPM33 IC belongs to an ASSP family of mixed signals designed for high accuracy measurement of power and energy in power line systems using a Rogowski coil, current transformer or shunt current sensors.

The device provides instantaneous voltage and current waveforms and calculates voltage and current RMS values, active, reactive and apparent powers and energies for each channel in compliance with accuracy standards (EN 50470-x, IEC 62053-2x, ANSI12.2x for AC watt meters).

The STDES-EMETER1PV1 single-phase smart meter is a fully assembled board developed for performance evaluation only, not available for sale.
