Overview

The ADS131M08MET evaluation module (EVM) uses the ADS131M08 and the MSPM0G1506SRHB to realize class 0.1 three-phase energy measurements based on IEC-62053, EN 50470 and ANSI C12 test methods. The ADS131M08 samples at 8kHz to measure the output of current transformers (CT) or Rogowski Coils (RC) along with a high-voltage resistive divider to measure the current and voltage of up to three phases. The EVM achieves high accuracy across a wide input current range (0.1A– 100A) and AC voltage up to 270V. The metrology software is implemented in the MSPM0-SDK and can be compiled with Code Composer Studio™ for further customization.
