Analogue front end monitors power quality
Designed to help extend the extend the health and life of industrial equipment while saving developers significant time and cost over custom devices, the ADE9000 is an integrated polyphase analogue front end with power quality analysis from Analog Devices.
It has embedded power quality algorithms, integrated with ADCs in one single device. The level of integration simplifies additional complex algorithm programming, reduces cost and component count, and increases speed to market while still achieving high accuracy and enabling EN61000-4-30 Class S for power quality, says the company. It can be used to detect disturbances and variations in the power supply (pollution) in equipment in factories, hospitals and commercial buildings, which can be susceptible to service interruption, premature failure, and long-term damage. In many cases, pollution in the power supply can go undetected before damaging expensive equipment. The ADE9000 enables designers to measure and analyse pollution in order to prevent disruptions and long-term damage, primarily for three-phase power meters.
The ADE9000 AFE integrates seven ADCs, a high-end reference, a DSP core, and proprietary algorithms into a single device. 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 provides real-time monitoring and harmonic analysis, including magnitude and phase information.
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.
