GZ Series programmable combination table
Product Details
GZ series programmable combination meter can display current, voltage, frequency, power, power factor and other combined parameters of electricity in the electrical circuit in digital direct reading mode, and conduct real-time measurement at the same time. Support single-phase, three-phase three wire signal or three-phase four wire signal input mode of power grid. It can also support analog quantity transmission, upper and lower limit start emergency signal and RS485 communication functions by installing different function modules. It is a series of products designed for power measurement and control needs of power systems, industrial and mining enterprises, etc.
