Electric energy meter LE-03MB CT v.2

Compliance

MID Directive 2014/32/EU
MID Certificate 0120/SGS0753

The LE-03MB-CT is an electronic, legalised (MID declaration) 3-phase AC electricity meter designed for semi-direct (using current transformers) or indirect (using voltage and current transformers) measurement in single-phase and three-phase networks. The meter allows the registration of imported and exported active and reactive energy and the monitoring of many additional network parameters such as voltage, current, active power, reactive power, apparent power frequency, power factor. The LE-03MB-CT v.2 meter is equipped with an M-BUS communication interface for remote meter reading and configuration. Configuration of the meter is also possible via the front panel with multifunction LCD display and touch buttons. The backlit LCD display makes it easy to read the measured values.

Functions

• MID-certified,
• bi-directional measurement of active and reactive energy,
• designed for installations

• 3-phase, 3- and 4-wire,
• 1-phase, 2-wire,
• current measurement using current transformers with secondary current of 1A or 5A, and primary current up to 9999A
• direct voltage measurement, or with the use of voltage transformers with a secondary side voltage of 100-500 V,
• recording of active and reactive energy consumption (total, export, import),
• monitoring of network parameters: voltages, powers, currents, power factor, frequency, power and current demand,
• M-BUS communication,
• two pulse outputs (one configurable),
• backlit LCD multifunction display,
• password protection for meter configuration.

Values recorded

• active energy (imported and exported),
• reactive energy (imported and exported).

Measured values

• active power, reactive power, apparent power, power factor,
• phase and phase-to-phase voltages,
• phase currents,
• power demand,
• percentage of voltage and current harmonics.

MeternetPRO
The MeternetPRO programme enables remote reading of statuses and readings of meters, multimeters, measuring transmitters, input/output expansion modules and other measuring devices communicating according to the Modbus RTU protocol. The application is an integral part of Excel. The read data are presented in a table in the programme. They can be freely shaped according to the software functions of the spreadsheet. Data exchange between the devices and the application is carried out via RS-485 network or LAN. The programme together with the database is installed on a special MT-CPU-1 server, which operates in the local network. The software user interface is a web application (website). The programme can be accessed via any web browser. In the case of a LAN with a public IP address, it is possible to configure the programme's operation and data reading via the Internet.

Subscriber billing module for electricity consumption
This is a subscriber billing module for electricity consumption or other recorded incremental values, e.g. water consumption, heat consumption, etc. It allows for the calculation of value increments in designated billing periods (time intervals). Cycles: monthly, weekly, daily, hourly. The module allows the creation of many individual and parallel reports.
