LE-03M-4Q – 3-phase, bidirectional, 4-quadrant electricity meter

LE-03M-4Q, 5902431679044

3-phase, bidirectional, 4-quadrant electricity meter, direct measurement up to 100A.
MID-certified.
Modbus RTU communication interface.

Compliance
MID Directive 2014/32/EU
Certificate No. 0598/MID/B/25/135

The LE-03M-4Q is a three-phase electricity meter with bidirectional measurement of active and reactive energy. The meter enables full 4-quadrant reactive energy measurement (import/export of inductive and capacitive energy). The device is designed for precise measurement of electricity consumption with the option of remote reading via an RS-485 communication interface supporting the Modbus RTU protocol.

Features

  • direct measurement of currents up to 100 A in a 3-phase, 4-wire system;

  • bidirectional measurement of active and reactive energy (import and export);

  • recording of total active and reactive energy consumption, broken down into import/export (active and reactive energy), and reactive energy consumption in all four quadrants.

  • MID certification;

  • measurement of current network parameters: voltage, currents, active, reactive and apparent power, power factor;

  • calculation of active and reactive power demand;

  • additional, resettable energy consumption meter;

  • remote reading via RS-485 communication port;

  • Modbus RTU protocol;

  • 2 configurable SO pulse outputs;

  • PIN code protection for settings;

  • backlit, multifunctional LCD display;

  • DIN rail mounting, 4-module wide housing.
