This product is used for real-time monitoring of key electrical factors in power lines, such as voltage, current, power, temperature, leakage, energy consumption, etc. It has functions such as remote control, early warning protection, short circuit protection, energy metering statistics, fault location, etc. It integrates the measurement of all power parameters, multi rate energy metering, four quadrant energy metering, harmonic analysis, and energy monitoring and assessment management. Multiple peripheral interface functions: with RS485/MODBUS-RTU protocol; With switch input and relay output, it can achieve the functions of "telemetry" and "remote control" of circuit breaker switches. It adopts an LED display interface, and parameter settings and control can be achieved through panel buttons. It can also be remotely controlled through mobile phones, making it very suitable for real-time power monitoring systems.
