The MCP3901 and PIC18F65J90 Energy Meter Reference Design is a fully functional IEC Class 0.5 compliant single-phase meter. This design does not use any transformers and requires few external components. The PIC18F65J90 directly drives the LCD and includes both an isolated USB connection for meter calibration and access to the device power calculations. The system calculates active energy, active power, RMS current, RMS voltage, reactive energy, reactive power, apparent power, and other typical power quantities.
The Microchip Energy Meter Single-Phase Software is used to calibrate and monitor the system and can be used to create custom calibration setups. The energy meter software offers an automated step-by-step calibration process that can be used to quickly calibrate energy meters.
