WFET-600S Electric Power Data Collector

General introduction:
WFET-600S electric power data collector is an acquisition device with acquisition and temporary storage function, which can realize the acquisition and temporary storage of data of electric meter with RS-485 interface, and use power line carrier, micro power wireless or other channels to upload the data to the concentrator, i.e. meter reading channel switching.
