ARD00330: Single Phase, 110 ~ 240VAC, USB GUI


The Energy Monitoring PICtail™ Plus Daughter Board is a power monitor circuit that uses the highly integrated PIC18F87J72 single chip energy meter IC. This low-cost design does not use any transformers and requires few external components. It includes both an isolated USB connection for meter calibration and access to the device power calculation, and an isolated PICtail Plus connection for Explorer 16 Development Board and other board developments.

The system calculates the Active Energy, Reactive Energy (both forward and reverse), Active Power, Reactive Power, Apparent Power, Root Mean Square Voltage (VRMS), Root Mean Square Current (IRMS), and other typical power quantities.

The Microchip Energy Meter 1-Phase Software used with this board calibrates and monitors the system. It can also be used to create custom calibration setups. For some accuracy requirements only a single point calibration may be required. The software offers an automated step by step calibration process that can be used to quickly calibrate energy meters.
