Z-series network power meter

Product Details

product description

summary

The Z series network power meters are used for continuous monitoring and control of distribution systems. It can measure various commonly used power parameters, reactive energy, and demand, and can perform remote control, over limit alarm, and analog transmission output function. DO output can be used for over limit alarm or remote control. The threshold value for the alarm can be programmed. All data can be read out through the RS-485 communication port using the MODBUS protocol, and the switch input DI can be used to monitor the status of the switch. The Z series power meters combine high-precision electricity measurement, intelligent energy metering and management, and a simple human-machine interface.
