Meters and Measurement Devices for Exact Consumption Data Acquisition
This multifunctional power meter is a three-phase four-wire smart power meter, specially designed for the electrical power monitoring and control demands in power supply and distribution systems. This power meter measures active and reactive energy and all the common electric power parameters, including three-phase voltage, three-phase-current, active power, and more. In addition, this meter also features a number of features, including the accumulation of electric energy, electric energy pulse output, limit alarm, input and on-off output, transmitting output of analog, network communication and much more.
Application
Multifunctional power meters are applicable to a variety of control systems, energy management systems, substation automation, distribution network automation, industrial automation, intelligent building, distribution boxes and switch cabinets.
