Single-Phase Active and Reactive Energy Meter, Modbus RTU, Multi-Tariff. LE-01MW

LE-01MW is a single-phase, electronic energy consumption meter in a multi-tariff version (4 zones) with a backlit LCD display. The device measures active and reactive energy (consumed/returned), allows for registration in 4 tariff zones thanks to the built-in real-time clock with battery backup, and provides data via the RS-485 interface with Modbus RTU protocol.

The manufacturer of the device is F&F Filipowski sp.k., a company offering measuring equipment and remote reading systems. In the manufacturer's documentation, compliance of the meter with the MID Directive 2014/32/EU is declared, and service software LE Config and the remote reading system MeternetPRO are provided.
