N43 network parameter meter

  • Measurement in 3 phase 4 wire/3 wire balanced and unbalanced systems.
  • For direct and indirect measurements.
  • The measurement of: rms values of voltage and current, active, reactive and apparent power, active, reactive energy, power factors, frequency.
  • Indications considering values of programmed ratios.
  • Backlit LCD dedicated screen.
  • Digital transmission to the master system through the RS-485 interface (MODBUS).
  • Configurable alarm outputs.
  • The pulse output for monitoring of 3-phase active energy.
  • USB for configuration by using free eCon software.
