Design files

Overview

TIDM-3PH-ENERGY5-ESD implements an ANSI/IEC Class 0.5 three-phase energy measurement system with enhanced electrostatic discharge (ESD) protection. The design also features communications through ZigBee™ connectivity. The energy measurement system on chip (SoC) is used to perform all metrology functions and sends active power results to the CC2530EM add-on board. You can use the companion in-home display reference design (TIDM-LOWEND-IHD) to display results remotely.

This reference design uses MSP430F67641A and can also be used with MSP430F67641.

Features
  • Three-phase energy measurement system which exceeds Class-0.5 accuracy requirements from ANSI and IEC
  • Passed IEC 61000-4-2 level-4 air discharge tests (see design guide for details)
  • Energy library firmware calculates all energy measurement parameters including active and reactive power and energy, RMS current and voltage, power factor and line frequency
  • Support for ZigBee® communication to in-home display or connections to Wi-Fi®, wireless M-Bus, and IEEE-802.15.4g add-on communications modules
  • Automated or manual switching between main and auxiliary power sources for metrology engine
