The MCP39F521 Power Monitor Demonstration Board is a fully functional I2C bus single-phase power and energy monitoring system. Up to four different devices can be placed on the same I2C bus through address select pins. The system calculates and displays active power, reactive power, RMS current, RMS voltage, active energy (both import and export), and four quadrant reactive energy.
It connects easily through USB to the “Power Monitor Utility Software” that offers automated control to allow you to easily experiment with all system configuration settings such as zero crossing detection options and event configurations, among many others.
The “Power Monitor Utility” software can also be used to and be used to create custom calibration setups. For most accuracy requirements, only a single-point calibration is needed. The energy meter software offers an automated calibration process that can be used to quickly calibrate energy meters and allow you to experiment with different calibration procedures.
