Integrated Circuit K1987PV014 for Accurate Single-Phase Energy Measurement

The integrated circuit K1987PV014 (NRTSAFE3A) is designed for use in single-phase electricity metering devices, includes three channels of analogue-digital conversion of currents and voltages, performs their statistical processing and transfer of results to the main calculator of the device.

The microcircuit provides:
- active and reactive power calculation for two channels simultaneously;
- active and reactive energy calculation;
- simultaneous calculation of RMS values of currents and voltages;
- frequency calculation in the voltage channel;
- event interrupt generation;
- input of calibration corrections;
- control of voltage output beyond the specified levels (SAG, PEAK);
- connection via UART interface.
