Electricity energy meter LE-03MW

Electricity energy meter LE-03MW

LE-03MW

3-phase, 2-wire, tariff to direct measurement.
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.

Characteristis of the device

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;
* 2Ă— SO pulse outputs with a programmable number of pulses per kWh / kvarh.
* multifunction LCD display.
