（1 )  Setting Function 

          Set current transformation ratio, target power factor, switching threshold, switching delay, capacitor configuration, harmonic voltage total distortion rate protection setting, harmonic current total distortion rate protection setting, communication parameters, etc. 

          The setting parameters are automatically saved and will not be lost after power failure.

（2 )  Reactive power compensation function 

         The sampled physical quantity is reactive power, with high compensation accuracy and no switching oscillation. 

         It has two operating modes: manual switching and automatic switching. 

         Logic switching mode, the capacitance of each group can be set freely. 

         The control output can be adapted to switching components such as electronic switches, composite electronic switches or synchronous switching switches. 

         Control output contacts 1-16 (24) channels, each DC 12V 20mA. 

（3 )  Protective function 

         It has protection functions such as phase loss, undervoltage, overvoltage, and over-harmonics.

（4 )  Communication function 

         It has RS485 data transmission interface and supports MODBUS communication protocol. Through its connection with a computer/meter reading machine or terminal and other upper computers, it can detect the relevant parameters of the power grid in real time, set parameters, and work.

Make a pleadingIt can modify the preset parameters and realize the collection and exchange of various data information locally or remotely.
