The LE-03MQ-CT energy meter is a three-phase, electronic meter that complies with directive 2004/22/EC and has certificate 0120/SG S0216. It is designed for measuring AC energy in single or three-phase in a semi-intermediate system.

The quality energy meter is ideal for displaying and recording consumed energy, as well as for monitoring supply parameters. It supports remote reading via RS-485 wired network.

It works with current transformers (CT) with secondary current of 1A or 5A and its configuration is done through the setup menu on the front display and its communication port, according to the programmed Modbus RTU functions.
