Multi circuit energy meter programmable intelligent meters, adopting AC sampling technology, can directly or indirectly measure electric voltage and current of single-phase or three-phase grid. Multi circuit power meter can be used for local display, and connecting industrial control devices to form a measuring control system.

Multi Function Energy Meter Types

AMC16Z series IDC monitoring module
Multi Circuit 48 Channel Energy Meter monitoring data center.

ADW210
ADW210has various expanded function modules for communication, measuring of temperature&residual current, DO/DI switch. Meanwhile, a 3-phase energy meter can monitor 4xthree phase circuits in total which means just 1 ADW210 can monitor 12 loads at the same time.
