Scope of application 
Z Series Network Power Meter for continuous monitoring and control of power distribution system. Can measure a variety of commonly used power parameters, there is reactive power, demand, can be remote control, the more limit alarm, and analog output transmission function. DO output can be used for over-limit alarm or remote control. The alarm threshold can be remotely controlled device. All data can be read by the MODBUS protocol via the RS-485 communication port. The digital input D1 can be used to monitor the status of the switches. The Z-Series combines high-precision power measurement, intelligent energy metering and management, and a simple human-machine interface.
