Scope of application 

HF Series Network Power Meter for continuous monitoring and control of distribution system. With analysis of 2-31 times the harmonic, phase / line voltage total harmonic distortion THD, current total harmonic distortion THDi, three-phase voltage unbalance ßU, three-phase current imbalance ßl. Can measure a variety of commonly used power parameters, active energy reactive energy, demand, can be remote control, the more limit alarm, and analog output function. And also has 8 hours 4 rate time-sharing measurement function. DO output can be used for over-limit alarm or remote control. The alarm threshold can be remotely controlled device. All data can be read by the MODBUS protocol via the RS-485 communication port. The digital input D1 can be used to monitor the status of the switches. Hf series of instruments will be high-precision power measurement, intelligent energy metering and management and simple man-machine interface together.
