Microchip Technology ARD00385 Data Sheet
MCP3911
Part Number: ARD00385
Devices Supported:
MCP3911
MCP3911
Summary Description:
The MCP3911 and PIC18F85K90 Single-Phase Anti-Tamper Energy Meter is a fully functional single-phase meter
with enhanced capabilities, such as battery backup, RTC and anti-tamper features. The two current channels are
measured with the MCP3911 device and the voltage channel is measured with the 12-bit SAR ADC integrated in the
microcontroller. This design has two sensors for the current measurements: a current transformer and a shunt. The
PIC18F85K90 microcontroller directly drives the LCD and communicates via UART with the MCP2200, offering an
isolated USB connection for meter calibration and access to the device power calculations. The system calculates
active and reactive energy, active, reactive and apparent power, power factor, RMS current, RMS voltage and the
line frequency. The Microchip Energy Meter Software is used to calibrate and monitor the system.
