This is the software for the MCP3909 3-Phase Energy Meter Reference Design.
The MCP3909 3-Phase Energy Meter Reference Design is a fully functional Flash MCU based 3-phase energy meter. The meter comes populated with components for a 220V, 5(10)A system complete with plastic IEC compliant energy meter case. The case contains high voltage line and load screw terminals for direct connection to mains voltage or to energy meter calibration equipment. The 3-phase energy meter calculations are Flash based using 7K of PIC18F2520 program memory. The calculations include active energy pulse output, active power, apparent power, RMS current, and RMS voltage. There are over 100 serially accessible output registers containing power quantities, in Flash. For calibration, there are registers including offset, gain, phase, and LSB correction for all power and energy quantities, in Flash. All registers are accessible through RS-232 and USB.
