Mercury 203.2Ò
Electricity meters are designed for commercial registration of active energy in one-phase AC circuits and operate both autonomously and as a part of AMM.
Functionalities:
- Measurement, registration, storage, output to LCD display and transmission through interfaces data as follows:
- energy with accrued total under each tariff;
- energy with accrued total by tariffs sum;
- energy by the beginning of each of previous 12 months;
- energy by the beginning of each of previous 12 months by tariffs sum;
- • The internal meter tariff rater of specifications as follows:
- tariffs - 4;
- êîëè÷åñòâî òàðèôíûõ çîí â ïðåäåëàõ ñóòîê - 8;
- tariff zones within 24 hours - 8 ;
- seasons - 12;
- Measurement, output to LCD display and transmission through interfaces power mains parameters as follows:
- active power instantaneous values and fixed peak;
- phase current and voltage actual values and their peaks;
- mains frequency
- Active power and energy limits setting and load shed if limits are exceeded.
Management by means of:
- Pulse output;
- Built-in relay (for meter with the «Î» index in reference designation);
- Load shed output (for meter with the «K» index in reference designation);
- Measurement and storage half-hour active energy power edge (power profile). Archive overflow time - 31 days.
- Event log (ringed, 64 records per each event) to fix:
- meter switching on/off time
- meter terminal and upper covers opening/closing time
- meter software upgrades date and time.
|
Construction features:
- replaceable interface modules to achieve the best flexibility in data collection network structure |
- load shed built-in relay |
 |
|
| Technical Specifications |
- Two current sensors – shunt (registers DC component) in phase circuit and current transformer in zero circuit;
- Built-in interfaces – optical port;
- Motherboard interfaces - RS485, CAN, GSM, PLC, RF modem;
- Interface inner power supply;
- Telemetry, verification and load shed management unit multi-functional pulse output;
- a separate load management output U=230V, I=40...300 ìÀ;
- Load shed built-in relay;
- LCD backlight;
- Electronic seal.

- current and voltage actual values and peaks;
- energy consumption value from putting in operation to the first date of each of 12 previous months under each tariff and by all tariffs sum;
- tariff zones switching time;
- current date and time;
- mean time between failures;
- battery operation time;
- meter reverse switching on;
- current inequality in meter sensors;
- power limit exceeding;
- relay shut-down.

Transmission of the following data about consumed energy with growing total |
- starting from beginning of meter operation on tariff and phases sum in case meter is programmed in one-tariff mode; |
- starting from beginning of meter operation on current tariff and phases sum on the moment of request in case meter is programmed in multi-tariff mode; |
• Receiving of the following data: |
- built-in modem network identifier; |
- command of temporal switch to auxiliary data transmission; |
- current date and time |
