Product Overview

The MCP3905RD-PM1 is a MCP3905A energy meter reference design a stand alone low cost energy meter. It can act as either a stand alone energy meter, or as the analog front end design for LCD microcontroller based meters. The MCP3905 design is specified with an energy measurement error of 0.1% typical across 1:500 dynamic range for high accurate energy meter designs. This reference design is compliant with EMC requirements per energy metering standards IEC62053 and legacy IEC61036, IEC1046 and IEC687. The device contains function blocks specific for IEC energy meter compliance, such as a no load threshhold and startup current. This board can be used as a reference design for single phase, residential meters.
  • Uses the new MCP3905A/06A devices
  • Demonstration board is a ready to use single chip low cost energy meter
  • Direct connection to line for energy meter, no transformers required
  • On board power supply circuitry
  • Resistive network and output LED for meter calibration
  • Resistor shorts for gain and frequency selection
