product details

overview

Network power meters are used for continuous monitoring and control of distribution systems. Capable of analyzing 2-31st harmonics, total harmonic distortion (THD) of phase/line voltage, total harmonic distortion (THDi) of current, three-phase voltage imbalance (ε u), and three-phase current imbalance (ε i). It can measure various commonly used power parameters, active and reactive energy, demand, remote control, over limit alarm, and has analog transmission output function. And it also has the function of 8 time periods and 4 rate time-sharing metering. DO output can be used for over limit alarm or remote control. The threshold value for alarm can be remotely controlled by the device. All data can be read out through the RS-485 communication port using the MODBUS protocol, and the switch input DI can be used to monitor the status of the switch. The HF series instruments combine high-precision power measurement, intelligent energy metering and management, and a simple human interface.
