Electric energy meter type MIR S-04

The meter is designed to measure active and reactive electric energy of forward and reverse directions, active, reactive and total power, active power factor, frequency, RMS values of voltage and current in three-phase four-wire or single-phase alternating current circuits, as well as to measure indicators of electric power quality.
The meter is designed to organise multi-tariff electricity metering.
The meter can be used to disconnect the consumer from the power network. The meter has a possibility of physical (hardware) blocking of the consumer disconnection relay operation, which allows the meter to be used at critical infrastructure facilities.
