RPCF series reactive power automatic compensation controller, based on **-digit micro processor, adopt Fourier progression decompose arithmetic, to get power fundamental wave data, the controller specially used for compensating reactive power in the power system with harmonic wave source. All components are of surface mounting technology, regurgitant solder, multi-stage inspection, these will make all RPCF controllers work steadily and reliably. RPCFC type has RS**5 port, standard protocol. It can be used as network meter.
