ADE7858AACPZ

数据采集ADC/DAC – Polyphase Multi functn EnergyMetr IC

Polyphase Multifunction  Energy Metering IC

GENERAL DESCRIPTION ADE7858AACPZ

The ADE7858AACPZ ADE7854A/ADE7858A/ADE7868A/ADE7878A are high accuracy, 3-phase electrical energy measurement ICs 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 (ADE7858A, ADE7868A, and ADE7878A), and apparent energy measurement and rms calculations.

FEATURES ADE7858AACPZ

Highly accurate; 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 (fundamental and harmonic) active, reactive,

and apparent energy and fundamental active/reactive

energy on each phase and on the overall system

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
