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 an external analog integrator for current measurements.
The ADE9430 power quality monitoring IC can be used to determine the amount of harmonics fed to a grid by inverter-based resources, including solar Photovoltaics, Energy Storage Solutions (ESS), and bidirectional EV chargers. By monitoring the disturbances on the grid, the solution allows better diagnostics on optimizing distributed energy resources that can be added to achieve a more reliable clean energy grid.
The Analog Devices Inc. ADE9430 Power Quality Monitoring IC is housed in a 40-lead lead frame chip scale package and is RoHS compliant.
