Northern Design Multicube Modular Single and 3 Phase Measurement Module Up to 20 Meters in 1 with additional modules. Requires multicube modular master unit Minimum 2 x 3 phase or 1 x single phase circuits with measurement module Alternative master with logger Optional pulse output modules Requires Multicube Modular Master or Multicube Master with Logger Optional 12 way pulse/alarm digital output modules Nominal current up to 0.383V (For 0.333V CT Input) and nominal voltage up to 240V L-N 415V L-L Graphic Display Optional RS485 or Ethernet communication up to 19,200 bit/s True RMS measurement of currents and voltages 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, reactive power, power factor, harmonics, etc.) from the measured signals.
