Description
GY7 Single and Three-Phase Power Meter
GY7 series 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 combined parameter).
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. Parameter setting and control can be realized through panel keys or communication, which is very suitable for the real-time power monitoring system.
