Compliance
Directive: 2014/32/EU
Certificate number: 0120/SGS 0216
Purpose
The LE-03MQ CT is a static (electronic) calibrated single-phase or three-phase alternating current electricity meter in a semi-indirect system. It is used for indication and registration of electric energy consumption and parameters of the power supply network with the option for remote reading through a wired RS-485 network.
The meter works with current transformers (CT) with a secondary current of 1 A or 5 A.
The meter is configured via the configuration menu accessible from the front panel and via the communication port according to Modbus RTU software functions.
