3-phase electricity meter | Mercury 234 ART-02 PO | Russia

Mercury 234 ART-02 RO meters are designed for single- or bidirectional multi-tariff metering of active and reactive electrical energy and power, as well as measuring the parameters of the electrical network in three-phase three- or four-wire AC networks with subsequent storage of accumulated information, event generation and transmission of information to data collection centers of ASUE systems. They are operated independently or as part of any information and measurement systems of technical and commercial accounting. The meters are designed for indoor use and can be used in places with additional protection from environmental influences (installed indoors, in a cabinet, in a flap). FEATURES: Measurement, accounting, storage, output to the LCD and transmission via the interfaces of active and reactive electricity separately for each tariff and the amount for all tariffs for the following time periods: the energy of everything from the reset of readings; energy at the beginning of the current and 123 previous days; energy at the beginning of the current and 36 previous months; energy at the beginning of the current and previous year; expense for the current and previous days; expense for the current and 11 previous months. Quadrant-by-quadrant accounting of reactive energy in bidirectional meters. A tariffier with the ability to set a separate schedule for each day of the week for 4 tariffs in 16 time zones of the day. Each month of the year is programmed for an individual tariff schedule. The minimum interval of the tariff within a day is 1 minute. The function of phase-by-phase multi-tariff accounting. Accounting for technical losses in power lines and power transformers. Measurement of electrical network parameters: instantaneous values of active, reactive and total power for each phase and for the sum of phases, indicating the direction of the full power vector; effective values of phase currents and voltages; values of angles between phase voltages; network frequency; power coefficients for each phase and for the sum of phases. Power profile and power profile of technical losses with an arbitrary averaging time from 1 to 60 minutes. The storage depth is 170 days for an averaging time of 30 minutes. Fixing the morning and evening maxima of active and reactive power at a given interval from 1 to 3600 seconds with a monthly schedule. Logging of events, including events of electricity quality indicators. The ability to connect backup power (5-12 V DC). The presence of multifunctional pulse outputs, including with a load control function. Automatic self-diagnosis with error indication. The presence of a built-in relay for 60 (100) A. Two non-volatile electronic seals. Recording of unauthorized impacts in non-erasable event logs. Multifunctional LCD with backlight and display of OBIS codes of displayed parameters. Indication of parameters on the LCD when the power is turned off. The ability to work on Mercury, DLMS/COSEM, SPODES protocols. The possibility of implementing Mbus, ModBus protocols on request. technical specifications: Active /full power consumption by the meter voltage circuit at rated voltage: 1.5 W /9 V*A.
