  • The STCOMET is a device that integrates a power line communication (PLC) modem, a high-performance application core and metrology functions.

    The PLC modem architecture has been designed to target the EN50065, FCC, ARIB compliant PLC applications. Together with the application core, it enables the STCOMET to support the ITU-T G.9001, ITU-T G.9903 (G3-PLC®), ITU-T G.9904 (PRIME), IEEE 1901.2, IEC 61334-5-1 (G1), CLC/TS 50568 (METERS AND MORE®) and other narrow band PLC protocol specifications.
    The metrology sub-system is suitable for EN 50470-1, EN 50470-3, IEC 62053-21, IEC 62053-22 and IEC 62053-23 compliant class1, class0.5 and class0.2 AC metering applications.
