Description

The ADE9430 is a highly accurate, fully integrated, polyphase energy and power quality monitoring device. Superior analog performance and a digital signal processing (DSP) core enable accurate energy monitoring over a wide dynamic range. An integrated high end reference ensures low drift over temperature with a combined drift of less than ?25 ppm/?C maximum for the entire channel including a programmable gain amplifier (PGA) and an analog-to-digital converter (ADC).The ADE9430 offers a complete power quality monitoring capability by providing instantaneous total as well as fundamental measurements on rms, frequency, phase angle, power factor active, reactive, and apparent powers and energies. Using the optional ADSWPQ-CLS Power Quality Library, advanced power quality features, such as dip and swell monitoring, power frequency, voltage total harmonic distortion (VTHD), and current total harmonic distortion (ITHD), are enabled. The one cycle rms, 10 cycle rms/12 cycle rms, and the optional ADSW-PQ-CLS Power Quality Library features are calculated according to IEC 61000-4-30 Class S. To request access to the ADSW-PQ-CLS, fill out the software request form at: Software Request Form | Analog Devices, where the target technology must be power quality monitoring and the processor/system on chip (SoC) is the ADE9430.The ADE9430 offers a resampled waveform of 1024 points per 10 cycles or 12 cycles. Resampling simplifies the fast Fourier transform (FFT) calculation of at least 40 harmonics in an external processor.The ADE9430 simplifies the implementation and certification of energy and power quality monitoring systems by providing tight integration of acquisition and calculation engines. The integrated ADCs and DSP engine calculate various parameters and provide data through user accessible registers or indicate events through interrupt pins. With seven dedicated ADC channels, the ADE9430 can be used on a 3-phase system or up to three single-phase systems. This device supports current transformers (CTs) or Rogowski coils when used with external analog integrator for current measurements.The ADE9430 absorbs most of the complexity in calculations for a power quality monitoring system. Combining a simple host microcontroller and the optional ADSW-PQ-CLS Power Quality Library, the ADE9430 enables the design of standalone monitoring or protection systems, or low cost nodes uploading data into the cloud.APPLICATIONS Energy and power monitoring Standards compliant power quality monitoring Protective devices Machine health Smart power distribution units Polyphase energy meters
