Technical details and manufacturing context for Measurement Core

Definition
The Measurement Core is the essential electronic subsystem of a Power Monitoring Unit responsible for sampling, conditioning, digitizing, and processing electrical signals (voltage, current) to calculate key power parameters such as active power, reactive power, apparent power, power factor, energy consumption, and harmonic distortion.
Working Principle
It operates by receiving analog voltage and current signals from sensors (e.g., CTs, PTs). These signals are conditioned (filtered, amplified), then converted to digital values by an Analog-to-Digital Converter (ADC). A digital signal processor (DSP) or microcontroller executes algorithms on this data to perform calculations, apply calibration factors, and generate the final measurement data for display, communication, or control purposes.
Common Materials
Silicon (for integrated circuits), FR-4 (PCB substrate), Copper (for traces and connectors)
Technical Parameters
  • ADC resolution (e.g., 16-bit, 24-bit), determining measurement precision. (bits) Standard Spec
Components / BOM
  • Analog Front-End (AFE)
