Electricity meter 3-phase LE-03MB F&F
Product description
LE-03MB is a static (electronic) calibrated single-phase or three-phase direct AC electricity meter. It is used for indication and registration of consumed electricity and mains parameters with the possibility of remote reading of indications through a wired network of the M-Bus standard. The meter is configured through the configuration menu accessible from the front panel and through the communication port in accordance with the software functions of the M-Bus.
Functions of the LE-03MB electricity meter

* indication of kWh/kvar (consumed/generated)
* indication of network parameters
* mID compliance
* m-Bus port and protocol
* pulse output SO
