Description
GY8 Multi-functional Power Meter
GY8 series multi-function electric instrument is for electric power systems, industrial and mining enterprises, public facilities, intelligent building electricity monitoring requirements, and designs a glaze of the intelligent electric measuring instrument, integrated full electric parameter measurement (each phase current, voltage, active power, reactive power, apparent power, frequency, power factor, and Jiu parameter), as well as the comprehensive management of electric energy metering and examination of (four-quadrant electricity measurement and time-sharing electricity statistics).
At the same time, it has a variety of peripheral interface functions for users to choose: RS485 communication interface based on Modbus-RTU protocol;4~20mA analog output can correspond to any measured electrical parameters; With switch input and relay output, circuit breaker switch can realize the “remote message” and “remote control” function; Active and reactive power pulse output function. Parameter setting and control can be realized through panel keys or communication, which is very suitable for a real-time power monitoring system.
