General Description
ADE7758 General Description
The ADE77581 is a high accuracy 3-phase electrical energy measurement IC with a serial interface and two pulse outputs. The ADE7758 incorporates second-order -∆ ADCs, a digital integrator, reference circuitry, temperature sensor, and all the signal processing required to perform active, reactive, and apparent energy measurement and rms calculations.
The ADE7758 is suitable to measure active, reactive, and apparent energy in various 3-phase configurations, such as WYE or DELTA services, both with three or four wires. The ADE7758 provides system calibration features for each phase, i.e., rms offset correction, phase calibration, and power calibration. The APCF logic output gives active power information, and the VARCF logic output provides instantaneous reactive or apparent power information.
