Product Description

The ADE7878AACPZ is a high accuracy, 3-phase Electrical Energy Measurement IC with serial interfaces and three flexible pulse outputs. The devices incorporate second-order Σ-∆ analog-to-digital converters (ADCs), a digital integrator, reference circuitry and all signal processing required to perform, total (fundamental and harmonic) active, reactive and apparent energy measurement and rms calculations. The device 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 8 kHz, these devices measure low ripple rms values, which are averaged internally and updated every 1.024s. The devices provide system calibration features for each phase, that is, RMS offset correction, phase calibration and gain calibration.
Supports EN 50470-1, EN 50470-3, IEC 62053-21, IEC 62053-22 and IEC 62053-23 standards
Compatible with 3-phase, 3- or 4-wire (delta or wye) meters and other 3-phase services
Supplies total active, reactive and apparent energy and fundamental active/reactive energy
0.1% Error (typical) in active and reactive energy over a dynamic range of 1000 to 1 at TA = 25°C
0.2% Error (typical) in active and reactive energy over a dynamic range of 3000 to 1 at TA = 25°C
Averaged RMS measurements available in low ripple rms registers
Supports current transformer and di/dt current sensors
Dedicated ADC channel for neutral current input
Estimated neutral current measurement by calculating the
RMS of the sum of the phase currents in all 3 phases
Supplies sampled waveform data on all 3 phases and on neutral current
Selectable no load thresholds for total and fundamental active and reactive powers, apparent powers
Highly accurate low power battery mode phase current monitoring for antitampering detection
Battery supply input for missing neutral operation
Phase angle measurements in current and voltage channels
Calibration frequency (CF) output directly drives LED and opto-isolators
1.2V (drift of ±5ppm/°C typical) Reference with external overdrive capability
