多相多功能電能計量相位信息集成電路ADE7758數(shù)據(jù)表

　　The ADE7758 is a high accuracy， 3-phase electrical energy measurement IC with a serial interface and two pulse outputs. The ADE7758 incorporates second-order Σ-Δ ADCs， a digital integrator， reference circuitry， a 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， with both three and four wires. The ADE7758 provides system calibration features for each phase， that is， 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.
