LE-03MW-CT Bidirectional electronic electricity meter for three-phase current, designed for semi-direct measurement

LE-03MW CT is a bidirectional electronic electricity meter for three-phase current, designed for semi-direct measurement. The integrated real-time clock allows for energy consumption measurement with different tariff zones.

The device is equipped with communication interfaces: RS-485 with Modbus RTU protocol and an optical port compliant with EN62056 (IEC1107) standard for remote reading and meter configuration.

## Technical Features

- Three-phase, bidirectional energy meter
- Semi-direct measurement (direct measurement up to 6 A)
- Energy measurement in 4 tariff zones
- Integrated real-time clock with backup battery for tariff zone switching
- Recording of total energy and broken down by consumption tariffs: – total active and reactive energy; – active and reactive energy broken down by individual quadrants
- 8 time bands dividing the day into tariff zones
- Possibility to account for energy according to specific schedules for weekdays and weekends
- Possibility to divide the year into 8 time intervals; in each interval, energy (for weekdays) can be accounted for 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 and resettable energy meter
- RS-485 port, Modbus RTU protocol
- Optical communication port compliant with EN62056 (IEC1107) standard
- 2 SO pulse outputs with programmable number of pulses per kWh/kvarh
- Multifunction LCD display
