Device for measuring energy in a three-phase power network. Continuously measures energy in a three-phase power network with up to 65 A. Calculates reactive energy, power, and power factor. Can be easily mounted on a DIN rail. The Z-Wave control allows for separate relay control as well as evaluation of measurement results. Suitable for residential, industrial, and utility applications. Reactive energy, power, and power factor under control. The smart meter measures energy directly in 2-wire networks by quickly querying voltage and current signals. A built-in microprocessor calculates reactive energy, power, and power factor using the measured signals. The device is designed for DIN rail mounting. The Z-Wave control enables the operation of separately available relays and the evaluation of device measurement results. Interoperable smart home products thanks to the Z-Wave protocol. The Z-Wave Alliance was founded in early 2005 by a group of leading home automation manufacturers who were all dissatisfied with the technological fragmentation that stifled the promise of the then-nascent home control industry. Their goal was to lead this industry from an uncertain future to a practical and widely adopted reality through common technological standards. Since its inception, the Z-Wave Alliance has proven to be a key player in the market for wireless home control. Thanks to the efforts of the founding companies of the Z-Wave Alliance and the more than 450 companies that have joined since, the promise of practical home automation is now a reality in the market.
