LE-01MR: single-phase energy meter in a direct system

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

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

Under the influence of current flow and applied voltage, the LE meter accurately measures the amount of electricity consumed. Energy consumption is indicated by the flashing LED (1000 pulses / kWh). In addition, the device measures network parameters and the temperature of its own system. The values are displayed cyclically on the LCD. The parameter changes every 3 seconds. Indicated values: active power (0.1 kWh); voltage (0.1 V); current intensity (0.1 A). The display is active if the instrument's power is on. If the power is off, the user can preview energy consumption [kWh] for 30 seconds by pressing the PRESS button.
Communication with the instrument, which functions as a SLAVE, takes place according to the Modbus RTU standard via an RS-485 serial port. The converted register values yield results consistent with the indications on the instrument's display. Each indicator is identified by a unique address assigned by the user.

#### LE-01MR version 2

Version 2 of the device has different modbus registers 
which can be found in the datasheet on this page: LE-01MR v.2 User Manual EN
