Used for commercial and technical registration of forward and reverse active and reactive energy and four-quadrant reactive energy consumption in three- and four-wire AC circuits of 3x57.7/100V or 3x120-230/208-400V voltage, 1 to 5A rated current, 10A maximum current, 50Hz frequency.
Meters have two equally foregrounded galvanically independent RS-485 interfaces and an optical port. Can be used as part of two automated power registration systems simultaneously, or as part of monitoring system. Support Ñ�Ò-4TM.02-compatible protocol.
Several designs of the meters are possible, varying in accuracy class, rated voltage, number of interfaces and availability of backup supply unit.
The most complete set includes 4 pulse outputs, two RS-485 interfaces, an optical port, backup supply unit, HASP.
o Digital processing of incoming analog signal
o Built-in tarifficator
o Two equally foregrounded galvanically independent RS-485 interfaces
o Real-time clock
o Four galvanically independent configurable pulse outputs
o HASP
o Keeping events log, power supply quality log, status log
o Backup supply unit

Following parameters can be programmed via / viewed at the RS-485 interface and optical port:
- rate of exchange by RS-485 channel (disabled for optical port);
- 1st and 2nd level access passwords;
- positioning name;
- network address;
- voltage and current gain coefficients;
- power integration period for making load graphs ranging from 1 to 60 minutes by two independent arrays;
- time synchronization and correction at broadcast query;
- tariff schedule, schedule for holidays and related days, morning and evening peaks;
- current time and date;
- DST adjustment time;
- programmable flags;
- indication modes and periods from 1 to 20 sec.;
- parameters for measuring power supply quality;
- forward and reverse active and reactive power thresholds;
- forward active power integration time for comparing with set boundary;
- masks of current measurement indication modes and basic parameters indication modes.
o The meters provide for multi-tariff registration of forward and reverse active and reactive energy, as well as four-quadrant reactive energy in 8 tariff zones by 8 day-types in 12 seasons. Tariff zone increment – 10 minutes. Alteration of tariff-zones within 24 hours – up to 144. Tarifficator of the meter considers holidays and related days schedule.

o Registered forward and reverse active and reactive energy and four-quadrant reactive energy can be displayed at the indicator:
- total since zero reset;
- for current and previous year;
- for current and previous month;
- for current and previous 24 hours.
o Registered forward and reverse active and reactive energy and four-quadrant reactive energy can be viewed via connection interfaces:
- total since zero reset;
- for current and previous year;
- at the beginning of current and previous year;
- for current month and previous 11 months.
- at the beginning of current month and beginning of each previous 11 month;
- for current 24-hours and 30 previous 24-hour periods;
- at the beginning of current and 30 previous 24-hour periods.
o Two independent power profile arrays can be supported with programmable integration time from 1 to 60 min for forward and reverse active and reactive energy. Each power profile array with integration period of 30 min is stored for 3,7 months.
o Morning and evening peaks of forward and reverse active and reactive power can be registered for both power profile arrays using 12-seasons schedule.
o Instantaneous values (integration period is 1 sec.) of the following parameters cab be measured and displayed:
- active, reactive and vector power per each phase and phase total depending on current and voltage gain coefficients;
- phase-, inter-phase and positive-phase-sequence voltage;
- linear current, current waveform distortion factor, forward and reverse series current unbalance factor;
- each phase power factor and phase sum factor;
- circuit frequency;
- phase and inter-phase voltage waveform distortion factors
- forward and reverse series voltage unbalance factor;
- temperature inside the meter;
- time and date.
