LE-03MQ CT

Electric energy meter,

3-phase

Directive MID 2014/32/EU

Certificate number 0120/SGS0216

The LE-03MQ CT is a static (electronic) calibrated electricity me-

ter of single-phase or three-phase alternating current in a semi-

-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 RS-485 network.

The meter works with current transformers (CT) with a seconda-

ry current of 1 A or 5 A.

Configuration of the meter is done through the configuration

menu accessible from the front panel and through the commu-

nication port according to the software features of the Modbus

RTU.

Compliance

Purpose

Do not dispose of this device in the trash along with other waste!

According to the Law on Waste, electro coming from households free of charge and can

give any amount to up to that end point of collec� on, as well as to store the occasion of

the purchase of new equipment (in accordance with the principle of old-for-new, regard-

less of brand). Electro thrown in the trash or abandoned in nature, pose a threat to the

environment and human health.

The indicator has a SO+/SO- pulse output. This allows you to

connect a pulse meter-reading pulses generated by the counter.

For proper operation of the indicator is not required to connect

additional devices.

The meter has sealable input and output terminal covers to pre-

vent any attempts to bypass the meter.
