Analog DevicesEVAL-ADE7878EBZDevelopment Kits and Tools

The evaluation board contains an ADE7878 and a LPC2368 microcontroller. The ADE7878 and its associated metering components are optically isolated from the microcontroller. The microcontroller communicates with the PC using a USB interface. Firmware updates can be loaded using one PC com port and a regular serial cable.

The evaluation board has been designed so that ADE7878 can be evaluated in an energy meter. Using appropriate current transducers, the evaluation board can be connected to a test bench or high voltage (240Vrms) test circuit. On-board resistor dividers networks provide the attenuation for the line voltages.

The ADE7878 is a high accuracy, 3-phase electrical energy measurement IC with serial interfaces and three flexible pulse outputs. The ADE7878 incorporates seven ADCs, reference circuitry and all signal processing required to perform total (fundamental and harmonic) active, reactive and apparent energy measurement, fundamental active and reactive energy measurement and rms calculations.
