1. Purpose

LE-03MB is a static (electronic), calibrated electricity meter of single-phase and three-phase alternating
current in direct system. It is used for reading and recording of imported electricity and parameters of
the power supply with the ability of remote reading through a wired M-Bus network. Configuration of
the meter is done through the configuration menu accessible from the front panel and through the
communication port according to the software features of the M-Bus.

2. Unit characteristics

2.1. Measured value

The unit can measure and display:

Line voltage and THD% (total harmonic distortion) of all phases;

Line frequency;

Currents, current demands and current THD% of all phases;

Power, maximum power demand and power factor;

Active energy imported and exported;

Reactive energy imported and exported.

2.2. M-Bus protocole and communication port

Meter has a port with support for M-Bus protocol.
The M-Bus communication port allows you to combine the counters in the remote reading network.

2.3. Pulse output

The meter has two pulse outputs for mapping the counting of active and reactive energy.
Output 1 - terminals 9/10 - programmable, can be set to work for active or reactive energy and
parameters: impulsing and pulse length.
Output 2 - terminals 11/12 - for active energy, impulsing is 3200 pulse / kWh.
