Produktoversigt
ADE7878A is a polyphase multifunction energy metering IC. It can also perform fundamental-only active and reactive energy measurement and rms calculations. A fixed function digital signal processor (DSP) executes the signal processing. The DSP program is stored in the internal ROM memory. This can measure active, reactive, and apparent energy in various 3-phase configurations, such as wye or delta services, with both three and four wires. Aside from regular rms measurements, which are updated every 8KHz, this device measure low ripple rms values, which are averaged internally and updated every 1.024 sec. The devices provide system calibration features for each phase, that is, rms offset correction, phase calibration, and gain calibration. The CF1, CF2, and CF3 logic outputs provide a wide selection of power information. It provides fundamental active and reactive powers.
