Functions

  • 3-phase, 2-way energy meter;
  • direct measurement up to 80 A;
  • energy measurement in 4 tariff zones;
  • built-in real time clock with battery backup to switch tariff zones;
  • registration of total and divided into consumption tariffs:
    • total active and reactive energy;
    • active and reactive energy divided into individual quadrants;
  • 8 time schedules dividing the day into tariff zones;
  • it can settle energy according to schedules specific for business days and weekends;
  • it can divide year into 8 time intervals; in each interval the energy (for weekdays) can be settled according to a different schedule;
  • indication of network parameters (voltages, currents, active power, reactive power, apparent power, power factor, frequency);
  • calculation of power demand for individual tariffs;
  • an additional, resettable energy consumption meter;
  • compliance with MID;
  • RS-485 port, Modbus RTU protocol;
  • optical communication port compliant with EN62056 (IEC1107) standard;
  • 2× SO pulse outputs with a programmable number of pulses per kWh / kvarh.
  • multifunction LCD display.

CE declaration

A copy of the CE declaration is available for download from the website: www.fif.com.pl from the product subpage.

Conformity
Directive: MID 2014/32/EC, 0120/SGS0306
Norm: EN50470-1/3

Purpose
LE-03MW is an electronic, compliant with the MID Directive, 2-way electricity meter for three-phase electricity, designed for measurement in a direct system.
The built-in real-time clock allows energy consumption to be measured with different tariff zones.
The device is equipped with communication interfaces: RS-485 with Modbus RTU protocol and optical port compliant with EN62056 (IEC1107) standard for remote reading and configuration of the meter


Do not dispose of this device in the trash along with other waste!
According to the Law on Waste, electro coming from households free of charge and can give any amount to up to that end point of collection, as well as to store the occasion of the purchase of new equipment (in accordance with the principle of old-for-new, regardless of brand). Electro thrown in the trash or abandoned in nature, pose a threat to the environment and human health.
