TIDM-3PHMTR-TAMP-ESD

Three-Phase Metrology With Enhanced ESD Protection and Tamper Detection Reference Design

TIDM-3PHMTR-TAMP-ESD

Design files

Overview

This reference design implements an ANSI/IEC Class 0.2 three-phase energy meter with enhanced ESD protection. The design also features tamper detection to limit the feasibility of energy theft and communications through ZigBee™ connectivity.  The e-meter 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 MSP430F67791A and can also be used with MSP430F67791, MSP430F6779 and MSP430F6779A.

Features
  • Three-phase meter with tamper detection which exceeds Class-0.2 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
