Electric energy meters single-phase SM409

The meter is designed to measure active and reactive electrical energy of forward and reverse directions, active, reactive and total power, active power factor, frequency, RMS values of voltage and current in single-phase AC circuits, as well as to measure power quality indicators. The meter is designed to organise multi-tariff electricity metering. The meter is designed for operation in stand-alone mode and as part of automated systems of control and metering of electricity. 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.
