LE-01MR is a static (electronic) calibrated electricity meter of single-phase alternating current in a direct system. It is used for reading and recording of consumed electric energy and mains parameters with remote readout via a wired RS-485 network.

Measured values: Active power - AE+ [kWh], Phase voltage - U [V], Phase current - I [A], Frequency - F [Hz], Meter system temperature - T [°C]

Under the influence of flowing current and applied voltage, the LE meter accurately measures the amount of consumed electricity. Energy consumption is indicated by flashing LED (1000 pulses/kWh). In addition, the device measures the mains parameters and the temperature of its own system. The values are displayed cyclically on LCD display. Parameter changes every 3 seconds. Indicated values: active power (0.1 kWh); voltage (0.1V); current intensity (0.1A). The display is active if the meter power supply is on. If the power supply is off, user can preview the energy usage [kWh] for 30 seconds by pressing the PRESS key.
Communication with the meter working as a SLAVE is performed in accordance with Modbus RTU standard via RS-485 serial port. Converted registers values give results consistent with the indications on the meter display. Each indicator is identified by a unique address assigned by the user.
