This Z-Wave module is used for energy measurements in single-phase electrical power network and can be used in residential, industrial and utility applications. Meters measure energy directly in 2-wire networks according to the principle of fast sampling of voltage and current signals. A built-in microprocessor calculates energy, power and power factor from the measured signals. The module can be controlled through Z-wave network and it acts as repeater in order to improve range and stability of Z-wave network. It is designed to be mounted on DIN rail.
