LE-03MQ Electricity Meter with MID

Three-phase, direct, bidirectional, four-quadrant measurement of electricity and network parameters, compliant with the MID directive, RS-485 interface and Modbus RTU communication protocol.
LE-03MQ is a static (electronic) electricity meter calibrated for single-phase or three-phase alternating current in a direct system. It is used for indicating and recording consumed electrical energy and power supply network parameters with the possibility of remote reading of indications via a wired network using the Modbus RTU standard. The meter is configured through the configuration menu available from the front panel and through the communication port in accordance with the Modbus RTU programming functions.
