Resampling simplifies fast Fourier The ADE9000 is a highly accurate, fully integrated, multiphase energy and power quality monitoring device. Superior analog transform (FFT) calculation of at least 50 harmonics in an performance and a digital signal processing (DSP) core enable external processor. accurate energy monitoring over a wide dynamic range. An The ADE9000 simplifies the implementation of energy and integrated high end reference ensures low drift over temperature power quality monitoring systems by providing tight integration of with a combined drift of less than 25 ppm/C maximum for acquisition and calculation engines. The integrated ADCs and the entire channel including a programmable gain amplifier DSP engine calculate various parameters and provide data (PGA) and an analog-to-digital converter (ADC). through user accessible registers or indicate events through The ADE9000 offers complete power monitoring capability by interrupt pins. With seven dedicated ADC channels, the providing total as well as fundamental measurements on rms, ADE9000 can be used on a 3-phase system or up to three active, reactive, and apparent powers and energies. Advanced single-phase systems. It supports current transformers (CTs) or features such as dip and swell monitoring, frequency, phase Rogowski coils for current measurements. A digital integrator eliminates a discrete integrator required for Rogowski coils. angle, voltage total harmonic distortion (VTHD), current total harmonic distortion (ITHD), and power factor measurements The ADE9000 absorbs most complexity in calculations for a enable implementation of power quality measurements. The power monitoring system. With a simple host microcontroller, cycle rms and 10 cycle rms/12 cycle rms, calculated according to the ADE9000 enables the design of standalone monitoring or IEC 61000-4-30 Class S, provide instantaneous rms measurements protection systems, or low cost nodes uploading data into the cloud. for real-time monitoring. Note that throughout this data sheet, multifunction pins, such The ADE9000 offers an integrated flexible waveform buffer that as CF4/EVENT/DREADY, are referred to either by the entire stores samples at a fixed data rate of 32 kSPS or 8 kSPS, or a EVENT pin name or by a single function of the pin, for example, , when only that function is relevant. 1 Protected by U.S. Patents 8,350,558 8,010,304.
