PURPOSE

• Installation at the consumer's home metering units in standard in-house panels on a DIN rail;
• Multi-tariff metering of active and reactive electrical energy of forward and reverse directions in single-phase alternating current circuits;
• Operation autonomously or as part of the accounting system AIISKUE RRE.

MEASURED AND COMPUTED PARAMETERS

• Active and reactive energy of forward and reverse directions;
• Active, reactive and apparent power;
• Root mean square (rms) values of current and voltage;
• Power factor;
• Network frequency;
• PCE measurement in accordance with class S GOST 30804.4.30-2013:
•   - slow voltage and frequency deviations;
•   - random voltage dips and overvoltage.

INTERFACES AND COMMUNICATION

• Optical port;
• RS-485 (optional);
• self-organizing PLC network of G3 PLC or PLC Y-net technology (optional);
• self-organizing wireless network ZigBee 2.4 GHz (optional);
• Bluetooth (optional) allowing:
•   - reading parameters by mobile devices based on Android OS through the MIR DP application;
•   - reading and configuring parameters for devices based on Windows 10 OS using the Metering Device Configurator program;
• Graphic display with built-in backlight.
• Replaceable communication communication module.

REPLACEABLE COMMUNICATION MODULE (OPTIONAL)

• Complies with the requirements of PJSC ROSSETI;
• Supports communication in GSM networks (GPRS or LTE technologies);
• Possibility of connecting an external antenna (optional);
• Equipped with an energy storage device to transmit a triggered message when the power is turned off ("last gasp" function) (optional).

PECULIARITIES

The metering device supports hot-swapping of a replaceable communication module, making it possible to retrofit an already installed metering device with a module, or to move the module to another metering device;
The functionality of the metering device fully complies with the requirements of the Government of the Russian Federation No. 890 and the technical requirements of PJSC ROSSETI;
Data transfer protocol: DLMS/COSEM, SPODES;
Relay control override switch;
Russian-language text of the parameters displayed on the indicator;
Gateway function from the GSM network to the PLC and/or ZigBee network (“Accounting in MKD”);
Two current sensors: in phase and in neutral;
Protection against electricity theft:
- presence of a magnetic field sensor and an indicator of exposure to a magnetic field; - electronic seals for opening the housing cover, the terminal clamp compartment and the cover of the replaceable communication module compartment; - transparent covers of the terminal compartment, communication module and device housing; - differential current control; - three levels of access provide protection against unauthorized reconfiguration of the device.
Joint work with KPU allows:
  - automatically generate power quality monitoring protocols for the selected period;
  - create a protocol for checking the metering unit; - export logs, power profiles, diagnostic data, etc. to Excel tables;
  - export and import files to configure display operation, tariff schedules, special days tables, etc.
The overvoltage protection function allows you to quickly disconnect the consumer from the network when an overvoltage occurs lasting from several periods of mains voltage;
Possibility of installing an additional replaceable battery without removing the terminal compartment cover and disconnecting the control unit from the network.
The warranty period is 8 years.
