Счетчики Меркурий PLC

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 11 months;
energy by the beginning of each of previous 11 months by tariffs sum;

The internal meter tariff rater of specifications as follows:
- tariffs - 4;
- tariff zones within 24 hours - 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

Consumer power load can be switched off thought a built-in relay fitted into display unit. Power load switching-off can be carried out in three cases::
- A command received via radio interface;
- Power limit preset in meter was exceeded;
- Energy limit preset in meter was exceeded.
Event log (ringed, 64 records per each event) to fix:

meter switching on/off time
device opening/closing time;
parameterization date;

Construction features:

The meter structurally consists of two units – power transducer (below) and display unit (top). The power transducer is placed on external wires of a power line; this prevents possibility of unauthorized energy consumption by some customers. There is remote communication between power transducer and display unit which is conducted via radio interface.

Display unit is fitted with a built-in relay for switching-off consumer power load.
