Low-voltage reactive power compensation device

According to the voltage and reactive power of the power supply bus, the SD-BML series low voltage reactive power compensation device (APFC) adopts the power factor controller to automatically detect the active and reactive power of the system in real time, automatically switches the capacitor bank, and tracks the change of the load for reactive power compensation, thus providing the power factor, improving the power supply quality and reducing the power loss.
