This document is the user guide for the evaluation board of ADE7878 Energy Metering IC. It describes the features and functionality of the evaluation board, as well as the method to implement three-phase energy metering using the board.
The document is a user guide for the ADE7878 evaluation board. It details how to connect external transducers (current transformers or Rogowski coils) and voltage sources to the board's screw terminals. The guide explains the power supply requirements, including the need for separate 3.3V supplies for the microcontroller and the isolated metering components.
The text covers setting up the evaluation board as an energy meter, configuring analog inputs for current and voltage sensing, and managing communication between the microcontroller and the ADE7878 via a USB interface.
