Getting started with the STDES-EMETER1PV1 single phase smart meter
Introduction
The
STDES-EMETER1PV1
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
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
not available for sale.
