LE-03MW-CT Dual Tariff Three-Phase Bidirectional Electric Energy Meter with Modbus RTU Intermediate
Remote reading. Three-phase. Bidirectional. Tariff-based. RS-485 port + Modbus RTU. For semi-direct measurement. With programmable ratio.
Application
LE-03MW CT is an electronic, bidirectional three-phase electric energy meter designed for measurement in a semi-direct configuration. The built-in real-time clock allows for energy consumption measurement divided into different tariff zones. The RS-485 communication interfaces with Modbus RTU protocol and the optical port compliant with EN62056 (IEC1107) enable remote reading and configuration of the meter.
