Number of the meter
The meter is marked with an individual serial number, which
makes it possible to identify it unambiguously.
The marking is indelible (laser engraving).
Sealing
The meter has the option of sealing the input and output termi-
nals, preventing the meter from being bypassed.
Compliance
Directive: 2014/32/EU
Certificate number: 0120/SGS 0216
The LE-03MQ CT is a static (electronic) calibrated single-phase or
three-phase alternating current electricity meter in a semi-indirect
system. It is used for indication and registration of electric energy
consumption and parameters of the power supply network with
the option for remote reading through a wired RS-485 network.
The meter works with current transformers (CT) with a secondary
current of 1 A or 5 A.
The meter is configured via the configuration menu accessible
from the front panel and via the communication port according to
Modbus RTU software functions.
