NORWOOD, Mass.—Analog Devices, Inc. (ADI) today introduced a highly integrated polyphase analog front end (AFE) with power quality analysis designed to help extend the health and life of industrial equipment while saving developers significant time and cost over custom solutions. Achieving extremely accurate, high-performance power quality monitoring typically requires customized development, which can be expensive and time-consuming. The ADE9000 AFE is an off-the-shelf solution with embedded power quality algorithms and integrated with high-performance analog-to-digital converters (ADCs) in one single device.
The ADE9000 AFE integrates seven high-performance ADCs, a high-end reference, a flexible digital signal processing (DSP) core, and proprietary algorithms into a single convenient device. High accuracy is driven by the ADCs and reference which provide low drift over temperature and the highest accuracy over the widest dynamic range. Pre-programmed proprietary power quality software provide real-time monitoring and harmonic analysis, including magnitude and phase information. This enables timely and cost-saving corrective action when necessary. For power system meter designers who do not require the advanced power quality features of the ADE9000, the ADE9078 energy metering AFE is available for polyphase utility grade meter applications.
