Product Description

The ADE7978ACPZ is a high accuracy, 3-phase Electrical Energy Measurement IC with serial interfaces and three flexible pulse outputs. The ADE7978 incorporates all the signal processing required to perform total (fundamental and harmonic) active, reactive and apparent energy measurement and rms calculations, as well as fundamental-only active and reactive energy measurement and rms calculations. A fixed function digital signal processor (DSP) executes this signal processing. The ADE7978 measures the active, reactive and apparent energy in various 3-phase configurations, such as wye or delta services, with both three and four wires. The ADE7978 provides system calibration features for each phase, gain calibration and optional offset correction. The ADE7978 incorporates power quality measurements, such as short duration low or high voltage detection, short duration high current variations, line voltage period measurement and angles between phase voltages and currents.
Enables shunt current sensors in polyphase energy meters
Immune to magnetic tampering
Supports EN 50470-1, EN 50470-3, IEC 62053-21, IEC 62053-22, IEC 62053-23, ANSI C12.20
Supports IEEE 1459 standards
Compatible with 3-phase, 3- or 4-wire (delta or wye) meters and other 3-phase services
Computes active, reactive and apparent energy on each phase and on the overall system
Less than 0.2% Error in active and reactive energy over a dynamic range of 2000 to 1 at TA = 25°C
