Electricity energy meter LE-03MW CT

LE-03MW CT

3-phase, 2-wire, tariff to half indirect measurement.
LE-03MW CT is an electronic, 2-way electricity meter for threephase electricity, designed for measurement in a half indirect measurement.

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
* half indirect measurement (direct measurement up to 6 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;
additional, resettable energy meter;
* 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
