LE-03MQ-CT 3F Bidirectional Meter Semi-Indirect Modbus RTU1005A; MID
Three-phase, semi-indirect, bidirectional, four-quadrant measurement of electrical energy and network parameters, compliant with the MID directive, Modbus RTU communication interface.
Application
LE-03MQ CT is a static (electronic), calibrated meter for alternating current in single-phase or three-phase semi-indirect systems. It is used for indications and registration of consumed electrical energy and supply network parameters with the possibility of remote reading of indications via a wired RS-485 network.
