MCP3901 PIC18F65J90 Shunt Meter Reference DesignThe 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.Rated 560A 220V 3200 imp/kWh IEC62053-22 Class 0.5 Energy Meter Convenient USB connectivity for calibration and analysis achieved by MCP2200 add-on circuitry Low-cost shunt-based energy meter design Direct Drive LCD Active Power, Reactive Power, Apparent Power, RMS Current, RMS Voltage, Active and Reactive Energy Low-cost capacitive-based power supply design ### Kit ContentsMCP3901/PIC18F65J90 Energy Meter Reference Design USB Cable ### 能量/功率测量 - Microchip

The is a 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 energy meter 1-Phase software is used to calibrate and monitor the system, and can be used to create custom calibration setups. For some accuracy requirements, only a single point calibration may be needed. The energy meter software offers an automated step by step calibration process that can be used to quickly calibrate energy meters.
