Mercury 230 ÀRT


Meters are designed for registration of active and reactive energy in one direction in 3- or 4-wire networks of alternating current and operate either autonomous or within AMR.

 Basic functions:
  • Measurement, registration, storage, output to LCD monitor and transmission through interfaces IrDA, CAN, RS-485 of the following data:
    - quantity of registered active and reactive energy separately by each tariff and total of all tariffs
    • total from indications reset
    • for current day and for the beginning of a day
    • for previous day and for the beginning of a day
    • for current month and for beginning of a month
    • for each of 11 previous months and for the beginning of month
    • for current year and for beginning of a year
    • for previous year and for beginning of a year
  • Tarifficator of meter provides possibility of registration by 4 tariffs in 16 timing zones of a day for 4 types of days. Each month of a year is programmed with individual timetable. Minimum tariff working interval within a day – 1 minute
  • Possibility of straight direction active energy registration separately in each network phase by each tariff with growing total and by tariffs total with data transmission through wire interfaces.
  • Possibility of registering technical losses in power lines and transformers;
  • Additionally meter provides output to LCD indicator and transmission through wire interfaces of the following network values:
    • instantaneous values of active, reactive and full power by each phase and by phases total with indication full power vector direction
    • functioning values of phase currents, voltages, angles between network frequency phase voltages
    • network frequency
    • power factors by each phase and by phases total
  • Input of active power and energy limits and programmable control of external consumer switch off load devices in case limits are exceeded.
  • Transmission of measuring and registration results through interfaces CAN, RS-485, IrDA
  • Meters programming in the mode of phases summation “on module” to prevent energy theft if meter current circuits connection phasing is wrong.
Technical specifications
  • Accuracy class 0.5s, 1.0s
  • interfaces: CAN, RS-485, IrDA,
  • measuring power, currents, voltages, cos F
  • PLC modem can be embedded for data transmission on power line 220V (depending on modification)
  • two standard galvanic unbound telemetric outputs (DIN 43864), one for each energy type;
  • meters operate towards values increase in case of any wrong phasing of current circuits
  • load control through external circuits of commutation
  • electronic seal
