3 Phase Energy Meter Module
The LW-G03 is intended to work in LonWorks FT-10 networks and perform 3 phase energy and power measurement. It has 3 voltage and 3 current AC inputs.
The module accepts voltages in the range 0 - 500 Vac, and currents from 0 to 5 Aac. External current and voltage transformers are required to meter signals out of these ranges.
The analog digital converter has a 16 bit resolution and the overall accuracy is 0.2 %.
