Product Name: Sfere720C multi-functional power meter

Sfere720C is the family product of the Sfere720 power quality analyzer. It equipped with electrical variable measurement, energy metering and power quality analysis functions. Sfere720C also can be extended up to 4 externel modules in the back side of the device. In some purticular industrial spot, the analog module could transmit the 0-20mA analog signl to the Sfere720C to access into a complicated industrial control system or establish a independent energy consumption optimized system as well.
