The ZAMEL LEM-60 electricity meter is a three-phase measuring device designed to monitor network parameters and measure energy in electrical installations. The model supports two-way energy measurement, which is why m.in will work. in photovoltaic installations, where it is important to control both the consumption and energy transfer to the grid.

The device is equipped with the RS485 MODBUS RTU interface, which allows remote reading of the installation parameters. The counter allows you to monitor m.in. voltage, current, active, reactive and apparent power, frequency, power factor and imported and exported energy. With a maximum current of 100 A per phase, the LEM-60 is suitable for more complex domestic, technical and commercial installations.
