380V Reactive Power Manager Rpm 14 Programming Manual for power factor controller
General
RPCF series reactive power automatic compensation controller, Based on 16-digit microprocessor, adopt Fourier progression decompose brith-metic, 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, regurgitate solder,multi-stage inspection, these will make all RPCF controllers work steadily and reliably. RPCFC type has RS-485 port, standard protocol. It can be used as network meter.
