Mercury 201.8 TLO
Product code: 201.8 TLO
Mercury 203.2T
Product code: 203.2Т
APPLICATION
The meters are designed for unidirectional multi-tariff measurement of active and reactive electric energy and power, as well as electrical parameters in two-wired AC networks with subsequent accumulated data storage, generation of events and data transfer to the AMR/AMI system’s data collection centers.
The meters are designed for indoor operation and can be installed in the areas with additional environmental protection (installed inside premises, cabinets or boards).
MODIFICATIONS
The meter modifications are available with different rated and peak current, and additional functionalities which are not related to metrological perfomance.

The meter measures, stores, displaying on LCD and communicate information via different interfaces of active and reactive electrical energy independently by every tariff zone and cumulatively for all tariff zones for the following periods of time:
- total cumulative energy;
- energy at the beginning of the current day and 180 previous days;
- energy at the beginning of the current month and 48 previous months.
— TOU with the option of setting individual schedule for every day of the week and month based on 4 tariffs, 16 time zones per day. Individual tariffs schedule is set every month. Minimal interval of each tariff during 24 hours is 1 minute.
— Measurement of electrical network parameters:
- instantaneous values of active, reactive and total power;
- RMS of current and voltage values;
- network frequency;
- power factor.
— Power profile with a 30-minute integration period and storage period 6 months.
— Recording of current, voltage, active and reactive power peaks.
— Event logging.
— Plug-in interface modules: RS-485, GSM, NB-IoT, PLC, CAN.
—Multifunctional galvanically isolated pulse output including load control function.
— Automatic self-diagnosis with error indication.
— Built-in 60A relay.
— Two nonvolatile electronic seals.
— Magnetic field sensor.
— Recording of unauthorized impacts to the indelible event log.
— Multifunctional LCD with backlight.
— LCD indication of data without main power.
— No magnet sensitive elements in measurement circuits and power system.
