MCP3901 PIC18F65J90 Energy Meter

Microchip's MCP3901 and PIC18F65J90 single-phase energy meter reference design

MCP3901 PIC18F65J90 Energy MeterMicrochip's MCP3901 and PIC18F65J90 energy meter reference design is a fully-functional, IEC Class 0.5-compliant, single-phase meter. This low-cost 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 1-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.
