MAYAK 102AT

PURPOSE

Energy meters are designed for accounting of active energy in two-wire AC networks with the rated frequency of 50 Hz.
Energy meters may be used both in standalone mode and as part of automated measuring and information systems for electric power fiscal accounting (AMIS EPFA).

TECHNICAL FEATURES

  • Non-volatile RAM
  • Rate card structure - 4 rates, 8 day types, rate plan:         
             - for 8 day types and 12 months (a separate one for each weekday of a month with due account for holidays);
             - flat rate for the whole of the year per 8 day types;
             - flat rate for the whole of the year per single day.
     Capability to set up to 32 exceptional days.
  • Liquid crystal display (LCD) ensures cyclic representation of the following data:
             - current value of energy according to rates available;
             - total value of accumulated energy according to rates available;
             - date and time;
             - current active power (for reference only);
             - preset power limit;
             - value of energy since the start of the current half-hour;
             - value of monthly energy consumption per year according to each rate available;
             - effective rate;
             - rate card.
  • Communication interfaces optical port, radio modem (Zigbee equivalent) or PLC.
  • Programmable pulse output.
  • Load control function (relay or signal).
  • Enhanced security (two access levels common and individual passwords; capability to record date and time of the last energy meter disconnection from the power network, last energy meter switching on).

FUNCTIONAL CAPABILITIES

Non-volatile RAM of the energy meter provides for recording and storing of the following values:
  • running total of active energy measured according to rates available from the date of manufacture;
  • active energy measured at the beginning of each month according to rates available over a one-year period;
  • active energy measured for each half-hour of a month over a two-month period;
  • power switch on / switch off time;
  • time of channel opening and closing for writing;
  • date and time prior to and upon the adjustment;
  • date and time of terminal box cover and energy meter housing cover opening and resealing.

Energy meter provides the capability to write time of day rates, current time, weekday, date, month, year, energy and power limits, consumer category.

Energy meters provide the capability to read out the following parameters:

  • active energy consumed according to rates available;
  • active energy consumed in each month of a year according to rates available;
  • rate card;
  • current date and time.
