    รายละเอียดสินค้า / Product Details

    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
    Flexible I2C, SPI, and HSDC serial interfaces
    Less than 0.1% error in active and reactive energy over a dynamic range of 1000 to 1 at TA = 25°C
    Less than 0.2% error in active and reactive energy over a dynamic range of 3000 to 1 at TA = 25°C
    Less than 0.1% error in voltage and current rms over a dynamic range of 1000 to 1 at TA = 25°C
