LE-03MW CT
Electric energy meter,
3-phase, 4-tariff, 2-way
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.
Purpose
The LE-03MW CT is a static, (electronic), 2-way calibrated electri-
city meter of three-phase or three-phase designed for measure-
ment in a semidirect system.
A built-in real-time clock allows energy consumption to be me-
asured by different tariff zones. Equipped with communication
interfaces: RS-485 with Modbus RTU protocol and an optical
port compliant with EN62056 (IEC1107) allows remote reading
and configuration of the meter.
Configuration of the meter is done through the communication
port according to the software features of the Modbus RTU.
