Northern Design Rail310-M2 Series 3 x Single Phase Multifunction Meter 5 Amp CT Input Optional RS 232/RS 485 communication up to 19,200 bit/s RMS values of currents and voltages Measurements of active, reactive power, power factor, average current and voltage The meter is intended for measuring, and monitoring single-phase or 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 to the 30th Harmonic) from the measured signals.
