Static Three-Phase Multirate Energy Meter Milur 307 TSKYa.411152.007-01.XXX — RZP OJSC

"Static, unidirectional three-phase multitariff universal transformer or direct inclusion meter, with built-in microcontroller and with a variety of interfaces counting mechanism to exchange information with external devices.

The meter of direct inclusion is designed for accounting of active and reactive electric energy in four-wire AC networks with nominal voltage of 3x230/400V. The basic (maximum) current is 5(100) A.

The meter, switched on through a current transformer, is designed for accounting of active and reactive electrical energy in four-wire AC networks with nominal voltage of 3x230/400V. Rated (maximum) current is 5(10)A.

The meter, included through current and voltage transformers, is designed for metering of active and reactive electrical energy in four-wire AC networks with nominal voltage of 3x57.7/100V. Rated (maximum) current is 5(10)A.

The meter is produced in the case:

- 9mTN35 - mounting on the rail TN35 according to GOST R IEC 60715 (DIN-rail), width 157 mm (9 modules of 17.5 mm), IP51.

For each modification of the counters there is a release of versions containing the following additional devices or functions:

- additional communication interface (RS-485, RF868, PLC, PLC.G3/RF868, ZigBee);

- programmable load switching on/off control output.

Display of consumed electrical energy is carried out on the liquid crystal display (hereinafter - LCD) of the meter.

The meter displays readings directly in kilowatt-hours (kWh) when measuring active energy and in kilovar-hours (kvar-h) when measuring reactive energy.

reactive energy measurement. The amount of stored electricity is displayed as eight digits, with the three or two lower digits separated by a comma, representing thousandths or hundredths of kWh (kvarh) for transformer or direct current meters, respectively.

The LCD displays:

- values of accumulated cumulative total of active and reactive energy

for each (up to 8) tariffs with indication of the tariff number;

- total (for all tariffs) value of accumulated cumulative total active and reactive energy

consumed active and reactive energy;

- current active, reactive and total power for each phase and

total value (reference value);

- voltage and current for each phase (reference value);

- mains frequency (reference value);

- power factor per phase and total value (reference value); power factor per phase and total value (reference value); power factor per phase and total value (reference value).

value);

- phase shift between current and voltage in each phase (reference value); phase shift between current and voltage in each phase (reference value); phase shift between current and voltage in each phase (reference value).

value);

- phase shift between phase voltages (reference value);

- absence of phase voltage (flashing symbol for phase A, B or C);

- open key symbol (if the terminal block cover is not fitted);

- backup battery voltage (reference value);

- current time and date;

- network address of the meter;

- software version;

- software numeric identifier;

- date and time of the last access to the optional interface.

Meters provide registration and storage in non-volatile memory
