ARD00455, Схема мониторинга питания, бюджетный дизайн, автоматизированный пошаговый процесс калибровки

The ARD00455 is an energy metering and power monitoring demonstration board based on MCP39F501 single phase power monitoring IC. This low cost design does not use any transformers and requires few external components. The device calculates active power, reactive power, RMS current, RMS voltage, power factor, line frequency 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. 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.
