3 phase electrometers.
Electrometers with S0 (open collector) pulse output.
These electricity meters can easily be connected to the SM2-MU unit to obtain information about 1 measured energy.
Electricity meters with RS485 interface.
These power meters can be connected to the AB or YZ interface of the SM2-MU unit to obtain information not only about several measured energies (consumption, production, up to 4 tariffs) but also about other values (voltage, current, power, frequency) even for each phase separately.
Electric meters with LCD panel.
It is possible to order an electricity meter that will be configured to display the display - how many and which quantities and how quickly the display changes.
