Technical informations

The Lettel MAP4-34RJ is a multifunction energy meter designed to monitor up to 4 three-phase or 12 single-phase circuits. It offers a compact and efficient solution for energy management in industrial and tertiary installations.

Main features:

  • Measurement of active and reactive energies, imported and exported
  • Instantaneous measurements: line-to-neutral and line-to-line voltages, phase and neutral currents, active, reactive, and apparent powers, power factor, frequency
  • Network quality analysis: total harmonic distortion of voltage and current, individual harmonics up to the 31st order
  • Recordings: demands, extreme values
  • Fully programmable RS485 Modbus RTU communication
  • Pulse output on active energy
  • Backlit LCD display with simplified navigation
