Technical informations
The Lettel MCT4-3100 is a multifunction energy meter designed for three-phase (3P). It provides accurate and detailed measurement of key electrical parameters, facilitating energy management in industrial and tertiary installations.
Main features:
- Measurement of active and reactive energies, imported and exported
- Instantaneous measurements: line-to-line voltages (L-L), phase and total currents, active, reactive, and apparent powers, power factor, frequency
- Historical records of extreme values (minimum/maximum demands)
- Fully programmable RS485 Modbus RTU communication
- Pulse output on active energy (adjustable constant)
- 8-digit backlit LCD display with simplified navigation
