STMicroelectronics IO elektroměru STPM33TR, QFN-32L, počet kolíků: 32 kolíkový

The STMicroelectronics ASSP designed for high accuracy measurement of power and energies in power line systems using the Rogowski coil, current transformer or shunt current sensors. It provides instantaneous voltage and current waveforms and calculates RMS values of voltage and currents, active, reactive and apparent power and energies.

• Dual mode apparent energy calculation
• Instantaneous and averaged power
• Under and overvoltage detection and monitoring
• Overcurrent detection and monitoring
• UART and SPI serial Interface with programmable CRC polynomial verification
• Programmable LED and interrupt outputs
