Mercury 206
E-meters are designed to register active and reactive electric energy in single-phase AC circuits, and capable of operating both as stand-alone and in the structure of automated data collection systems.
Functionalities:
- Measurement, registration, storage, output to LCD and transfer via interfaces of data on registered active and reactive electric energy as follows:
- Energy with accrued total under each tariff ;
- Energy with accrued total by sum of tariffs ;
- Energy at the beginning of each of 12 last months under each tariff ;
- Energy at the beginning of each of 12 last months by sum of tariffs;
- Availability of the built-in tariff-rater with characteristics as follows:
- Number of tariffs - 4;
- Number of tariff zones within a day - 8;
- Number of day types - 8 ;
- Number of seasons в - 12;
- Measurement, output to LCD and transfer via interfaces of power line parameters as follows: :
- Instantaneous values of active and reactive power and fixed maximums;
- Effective values of phase current and voltage and their maximums ;
- Power line frequency
- Setting active power and energy limits and load shedding at overlimit or by operator's command. Control is performed in two ways:
- Abuse signal delivery to the meter pulse output ;
- Direct management of electric energy supply through the built-in relay (for meters with index «О» in reference designation)).
- Measurement and storage of half-hour power cuts of active energy (power profile). Archive storage depth before overwriting makes 31 days.
- Availability of Event log (circular by 64 records for each event) which fixes data as follows:
- The meter On/Off time
- The meter opening / closing time
- Time, date and a parametrization code.
|
Construction features:
|
- Control of indication
modes through
оптопорт.
- Load shed built-in relay |
 |
|
| Technical Specifications |
- Current sensor is a shunt (insensible magnetic field exposure registering constant component) in phase circuit;
- Availability of digital interfaces: optical port in any modification; optional RS485 (CAN), PLC-I;
- Internal or outside power of interface RS485 (CAN);
- Multipurpose pulse output for telemetry, verifications and load shedding management;
- Built-in load shedding relay at current 60А;
- Electronic seal;
- Terminal block with self-expanding terminal of power circuits chains;
- Fastening to a rack .

Meters display in LCD information as follows: |
- Number of the current tariff
- Energy consumption value for each kind from the operation beginning under each tariff and by all tariffs sum
- Current value of active power in load in kW or kVar
- Current values of current and voltage
- Energy consumption value from the operation beginning on the first day of each of the last 12 months under each tariff and by all tariffs sum
- Time of tariff zones switching
- Current time and date
- Operating time from start-up
- Battery operating time
|
Energy meter with PLС-modem in basic mode transmits uninterruptedly on power line the following data on consumed energy with increasing total without tenth parts kW*h: |
- Total from the moment of indication reset on tariffs sum provided that energy meter is programmed into one-tariff mode;
- Total from the moment of indication reset on current tariff provided that energy meter is programmed into multi-tariff mode;
|
Energy meters provide programming and reading by external computer through optikal interface or RS485(CAN) of the following values: |
