Purpose; Device Characteristics - F&F LE-03MW User Manual

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:
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.
