TIDM-THREEPHASEMETER-F67641

Design files

Overview

This design implements a complete smart meter design using the MSP430F67641 polyphase metering System on Chip. The design meets all requirements for ANSI/IEC Class 0.5 accuracy and the firmware provided calculates all energy measurement parameters. The F67641 SoC features 128KB of on-chip flash plus a 320-segment LCD controller for a single-chip solution to low-cost polyphase meter design challenges.

Features
  • Low-cost three-phase electricity meter for Class 0.5 accuracy
  • TI Energy Library firmware calculates all energy measurement parameters including active and reactive power and energy, RMS current and voltage, power factor, line frequency, fundamental and THD readings
  • Add-on communications modules for wireless communications standards such as ZigBee®, Wi-Fi®, Wireless M-Bus, and IEEE-802.15.4g. Both 2.4 GHz and Sub-1 GHz.
  • Built-in 160-segment display
  • Powered from three-phase line voltage
