Electricity meter LE-01MW v2

LE-01MW, 5902431672304

Product description

1-phase, 2-wire, 4-tariff,  MID compliance
The LE-01MW v2 is an electronic, compliant with the MID Directive, single-phase electricity meter, designed for measurement in a 2-wire direct system.

The built-in real-time clock allows energy consumption to be measured with 4 tariff zones.
The meter is equipped with RS-485 communication interface with Modbus RTU protocol allowing remote reading and configuration
of the meter.

MID Directive 2014/32/EU
Certificate 0120/SGS0571

Characteristics of the device

  • 1-phase energy meter;
  • Direct measurement up to 100 A;
  • DIN rail mounting (1 module);
  • Operate in one of two measurement modes:
    • measurement of imported and exported active energy;
    • measurement of imported and exported reactive energy;
  • Energy measurement in 4 tariff zones;
  • Built-in real time clock with battery backup to switch tariff zones;
  • Time schedules dividing the day into tariff zones;
  • It can settle energy according to schedules specific for business days and weekends;
  • Indication of network parameters;
  • Compliance with MID;
  • RS-485 port;
  • Modbus RTU protocol;
  • Backlit LCD display.

The LE-01MW meter precisely measures the amount of consumed electricity under the influence of flowing current and applied
voltage. Power consumption is indicated by the flashing LED. In addition, the meter measures the parameters of the supply
network and the temperature of its own system. The values are indicated cyclically on the LCD display. The display is active when the indicator power is on. The meter operates in the communication network as a Slave device. The communication takes place in accordance with the Modbus RTU standard via the RS-485 serial port. The read-out values of registers after conversion give results according to the indications on the indicator display.
