LE-03MW CT – user manual

1. Purpose

LE-03MW CT is an electronic, 2-way three-phase electricity meter, designed for measurement

in a semi-indirect system. A built-in real-time clock allows energy consumption to be measured

by different tariff zones. RS-485 with Modbus RTU protocol and optical port compliant with EN62056

(IEC1107) provide remote reading and configuration of the meter.

2. Device characteristics

3-phase, 2-way energy meter;

Semi-indirect current measurement (direct measurement up to 6 A);

Energy measurement in four tariff zones;

Built-in real-time clock with battery backup for switching tariff zones;

Registration of total and tariff-divided consumption of:

•total active and reactive energy;

•active and reactive energy divided into individual quadrants;

8 time schedules that divide the day into tariff zones;

Possibility of billing energy according to different weekday and weekend schedules;

Ability to divide the year into 8 time periods. In each period the energy (for working days) can

be billed 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;

RS-485 port, Modbus RTU protocol;

Optical communication port compliant 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 which

parameter group the value displayed in the numeric

field is associated with. 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 – reactive 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.

A list of displayed parameters is shown in the following table.
