ADE7868AACPZ, Analog Devices
ADE7854/7858/7868/7878 Series, Polyphase Multifunction Energy Metering IC, Analog Devices
The ADE7854, ADE7858, ADE7868, and ADE7878 from Analog Devices are high accuracy, 3-phase electrical energy measurement ICs with serial interfaces and three flexible pulse outputs.
Incorporated into these devices are second-order sigma-delta (Σ-Δ) analogue-to-digital converters (ADCs), a digital integrator and reference circuitry. In addition these ICs have the signal processing required to perform energy measurement and rms calculations. A fixed function digital signal processor (DSP) executes this processing, with the DSP program being stored in the internal ROM memory.
Features
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), and other 3-phase services
Supports current transformer and di/dt current sensors
Supplies sampled waveform data on all three phases and on neutral current
Selectable no load threshold levels for total and fundamental active and reactive powers, as well as for apparent powers
Battery supply input for missing neutral operation
Phase angle measurements in both current and voltage channels with a typical 0.3° error
