Electricity Meter

Electricity Meter

Today’s Electricity Meters are typically MCU based, connected, tamper proof sophisticated electronic devices optimized for individual target markets. While regional differences in AC voltage and frequency influence their integrated AC/DC power supply, connectivity and commissioning might differ with local municipalities or power providers, ranging from cellular modems, Power Line Communication to BLE for commissioning. A common topic for all E-meters are tamper detection and tamper immunity. This exemplary block diagram shows a single to multi-phase electricity meter using PrimAccurate flyback AC/DC converter, high-speed, very-low power DataFlash™ and FusionHD™ Flash memory, a GreenPAK based, customizable tamper detection and super-capacitor-based backup power control.
