1. Purpose
LE-03MW is an electronic bi-directional three-phase electricity meter, compliant with the MID
Directive, designed for direct measurement. The built-in real-time clock allows the measurement of
energy consumption divided into different tariff zones. Communication interfaces: RS-485 with
Modbus RTU protocol and optical port according to EN62056 (IEC1107) enable remote reading and
configuration of the meter.
2. Device characteristics
 3-phase bi-directional energy meter;
 Direct measurement up to 80 A;
 Energy measurement in four tariff zones;
 Built-in real-time clock with battery backup for switching tariff zones;
 Total and tariff-divided consumption registration:
 total active and reactive energy;
 active and reactive energy divided into individual quadrants;
 8 time schedules dividing the day into tariff zones;
 The possibility of settling the energy according to different schedules for working days and
weekend;
 The possibility of dividing the year into 8 time periods. In each period the energy (for
working days) can be settled according to a different schedule.
 Indication of network parameters (voltage, currents, active power, reactive power,
apparent power, power factor, frequency);
 Calculation of power demand for individual tariffs;
 Additional, resettable energy consumption meter;
 MID compliance;
 RS-485 port, Modbus RTU protocol;
 Optical communication port in accordance with EN62056 (IEC1107);
 2 SO pulse outputs with programmable number of pulses per kWh/kvarh;
 Multifunctional LCD display.

4.1. Description of the display elements
Current tariff indicator
Symbol - indicates to which group of parameters the value displayed
in the numeric field is related. It may be a tariff (T1, T2, T3 T4)
or phase (L1, L2, L3) indicator.
Unit of the value shown in the numeric field of the display.
Symbols have the following meaning:
kW - active power
kWh - active energy
kvarh - passive energy
VA and kVA - apparent energy
V - voltage
A –current
The numeric field of the display indicates the value of the frequency.
Data exchange via the communication interface.
Low battery indicator for the internal clock battery.
4.2. Control elements
Control buttons for changing the displayed value.
The list of displayed parameters is shown in the following table.
