Nero - Multi Protocol - Three Phase Smart IOT Electricity Meter

R7,999.00Price
Sales Tax Included

Details:

The multi-tariff three-phase electronic meter is designed for metering active and reactive energy in forward and reverse directions in three-phase four-wire AC circuits with a frequency of 50 Hz.

The meter is equipped with communication interfaces for operation in systems with remote sending of readings and possibility of simultaneous data collection using different communication technologies.

 

Features:

  • Sigfox, Lorawan, NB-IOT, Plug and Play & Nero UNB compatible
  • Active energy accuracy class 0.5S / 1; for reactive energy: 0.5 / 1;
  • Simultaneous collection of data via PLC and radio interfaces;
  • Communication interfaces: Radio (RF434 or RF868), GSM / LTE, RS-485, PLC, G3-PLC;
  • Removable GSM/LTE modem or DATD;
  • Records the mains frequency, current and voltage in each phase, angles between the vectors of phase voltages and vectors of phase currents of voltages, power factor in each phase;
  • Signals about tampering with the housing cover and the terminal block clipses, exceeding the energy and power limits;
  • Can be mounted on a DIN rail.

 

The Meter Measures and Displays:

  • Network frequency;
  • Current in each phase;
  • Voltage in each phase;
  • Angle between current and voltage in each phase;
  • Angle between phase voltages;
  • Power factor in each phase.


The Meter Controls:

  • Accounting for four energy profiles: active and reactive, forward and reverse directions with an interval of power integration of 1, 3, 5, 10, 15, 60 minutes;
  • Consumed active power direction with an interval power integration in 1, 3, 5, 10, 15, 60 minutes;
  • Instantaneous power consumption;
  • Active energy consumption limits;
  • Low current consumption;
  • Supply voltage;
  • Consumed currents;
  • Network frequencies;
  • Phase sequence;
  • Phase loss.

 

Lead Time:

1 - 5 Days.
