Description

Wireless energy meter for measuring electrical consumption in civil, industrial and service applications. Data is acquired by split core current transformers (TA).

The device measures voltage, current, instant power and energy consumption.

Thanks to continuous power, the device can also function as a ZigBee signal repeater and as a parent device for battery powered sensors.
