The PIC18F87J72 Single-Phase Energy-Meter Reference Design (Part # ARD00280) can be obtained through Microchip sales representatives for evaluation, today.
Featuring a shunt-based single-phase meter with energy-calculation firmware and GUI-assisted software calibration, the reference design enables calculation of active/reactive energy, forward/reverse energy, active/reactive/apparent power and RMS current/Voltage. Customers can reuse or customize the free firmware for their needs, which further shortens time to market and enables them to differentiate their products in the marketplace.
Additionally, the PIC18F87J72-based Energy Monitoring PICtail Daughter Board (part # ARD00330) can be plugged into Microchip’s Explorer 16 Development Board (part # DM240001) for easy development of energy-measurement and -monitoring devices.
The PIC18F87J72 Energy Monitoring PICtail Plus Daughter Board is a single phase energy monitor daughter board featuring the PIC18F87J72 high performance 8-bit MCU with 16/24-bit delta-sigma A/D converters. This low cost design uses a shunt for the current sensor in place of expensive current transformers. The PIC18F87J72 calculates active/reactive energy, forward/reverse energy, active/reactive/apparent power and RMS current/voltage. The Energy Monitoring PICtail Plus Daughter Board interfaces to the Explorer 16 Development Board (DM240001) where additional evaluation can be performed. Through the Explorer 16 Development Board, wired and wireless network connections can be made through other PICtail Daughter boards such as the Ethernet PICtail (AC164123) and the WiFi PICtail (AC164136-4).
