It can suppress ~th order harmonics, and can suppress specified order harmonics and suppress the target value of harmonics as needed.
Built-in reactive power compensation function, which can be set after it is put into use. It can filter out harmonics and reactive power compensation at the same time, and give priority to the filtering function
.
The filter can avoid over-compensation while filtering. The active filter can only filter without generating reactive power, completely avoiding over-compensation
. It can also be set by setting the target power factor. The remaining energy after filtering is used for reactive power compensation.
The active filter has complete protection functions, including overvoltage, overcurrent, short circuit, etc., and has system self-diagnosis function.
Equipped with a soft-start control loop to avoid excessive surge current at startup.
When the harmonic amount of the system load is greater than the filter's compensation capability, the filter can output the rated current according to the body capacity and continue to filter effectively without overloading.
The active filter has a color LCD touch screen (human-machine interface), which can set the working mode (harmonic compensation mode, reactive power compensation mode, etc.), parameter setting (transformation ratio setting, power-on mode setting, parallel capacity setting, display setting, etc.), harmonic compensation setting (successive compensation mode or full compensation mode), information viewing and other operations, which can display the operating status and the voltage and current information of each phase before and after compensation. , each harmonic
information, measurement data, fault alarm and other information.
The output filter of the active filter adopts a structure to connect to the power grid, so that its own high-frequency carrier will not feed back to the power grid, which will affect other systems. There is no
interference with the device.
