Northern Design Cube 400-M2-C Series 3 Phase Power Meter Optional 2 Pulse Input or Outputs Nominal current up to 6 A (For 5A CT Input) and nominal voltage up to 240V L-N Three Line Display Optional RS 232/RS 485 communication up to 19,200 bit/s RMS values of currents and voltages Measurements of active, reactive, apparent power and power factor Optional THD up to 15th Harmonic The meter is intended for measuring, analysing and monitoring single-phase or three-phase electrical power network. The meter records TRMS value according to the principle of fast sampling of voltage and current signals. A built-in microprocessor calculates measurands (voltage, current, frequency, energy, power, power factor, phase angles, etc.) from the measured signals.
