Product Overview

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.
  • Event notifications for over current, power, over/under frequency and temperature, voltage surge
  • Configuration through PC S/W, event notifications, gain calibration, EEPROM, calculation multipliers
  • 120V and 220V operation
  • Power monitoring accuracy capable of 0.1% error across 4000:1 dynamic range
  • Fast calibration routines
  • 512bytes user accessible EEPROM through page read/write commands
  • Non volatile onchip memory, no external memory required
  • Two wire serial protocol using a 2 wire UART interface supporting multiple devices on a single bus
