Mercury 203.2T LBO Electric energy meter, single-phase, multi-tariff

The meters are designed for commercial metering of active and reactive (since 2014) electricity in single-phase alternating current circuits and operate both autonomously and as part of an automated power supply system. Functionality: Metering of active and reactive energy in multi-tariff (up to 4 tariffs) or single-tariff modes. Storage, display on the LCD indicator and transmission via interfaces of the following accounting information: active and reactive energy on an accrual basis for each tariff and by amount; active and reactive energy at the beginning of each of the 12 previous months for each tariff and by amount; Storage of archival information read through digital interfaces: daily active energy profiles for 6 months; monthly sections of active energy for 4 years; Measurement, display on the LCD indicator and transmission via interfaces of the following power network parameters: instantaneous values of active and reactive power and the recorded maximum; effective values of phase current and voltage and their maximums; network frequency Load control by setting active power and energy limits and disconnecting the load when the limits are exceeded or at the command of the dispatcher. Control is carried out in two ways: pulse output; via a built-in relay (for a meter with the index “O” in the symbol). Formation of a load power profile in the form of an array of active energy powers averaged over 30 minute intervals. The archive storage depth is 6 months. Availability of an event log (circular with 64 entries for each event) in which the following are recorded: the time the meter was turned on, the time the device was opened/closed, time, date and parameterization code. Technical features: current sensor - shunt (takes into account the constant component) in the phase circuit; built-in interfaces: optical port; interfaces on daughterboards: RS485, GSM, PLC-II; internal power supply of the interface; multifunctional pulse output for telemetry, verification and control of the load shedding device; built-in load disconnect relay for current 60A; LCD backlight; electronic seal. The meters display on the LCD indicator: the number of the current tariff; the value of energy consumed since the beginning of operation for each tariff and the amount for all tariffs; current value of active power in the load in kW and maximum; current current and voltage values and maximums; the value of energy consumed from the beginning of operation on the first day of each of the previous 11 months for each tariff and the amount for all tariffs; time of switching tariff zones; current time and date; MTBF; battery operating time; inequality of currents in current sensors; exceeding the power limit; relay disconnection. In the designation of meters: MERCURY 203.2TR(,L,G) (O) B MERCURY – trademark of meter 203 – meter series 2 – device for displaying electricity – LCD T – internal tarifficator R (F,L,G) – interface No. 1 , namely: R - RS485 interface L - PLC modem G - GSM modem O - built-in relay B - LCD backlight The absence of a symbol in the name of the meter indicates the absence of the corresponding function.
