Z Series Network Power Meters are used in persistent monitoring and controlling for power distribution system. It can measure all common electric parameters, active and reactive electric energy demand. They can control and over-limit alarm in distance with the functions of analog value transmitting output and calculating the maximum demands.     DO output is used in over-limit alarming and long distance remote controlling. The limiting value of the alarming can be program controlled and configured. All the data can be read by RS-485 communication interface according to MODBUS Protocol and the switch value DI can be used for monitoring the state of the switch. Z series network power meters integrate the high precision electric parameter measurement, smart electric power measurement with management and simple human-machine interface.
