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.
Function features 1-On basis for fundamental wave reactive power, calculate the reactive power to be switched on, it can avoid switching shock of any forms, it can accurately display the power factor of system with harmonic wave. 2- High measurement accuracy, wide display scope. 3- Real time display general power factor and fundamental wave PF. 4- Real time displays the distortion rates of voltage and current. 5-Total 12 kinds of coding output can be chosen. 6- 16 circuits of output at maximum. 7- Human friendly interface, convenient operation. 8- Various control setting can be adjusted digitally, directly and easily. 9- Automatic and manual operations, two modes provided. 10 Over voltage and absent voltage protection provided. 11- Protection against superscalar of harmonic wave voltage. 12- Data not lost even if power shut down. 13- Current signal input resistance ≤ 0.01 Ω. 14- Communication function (MODBUS-RTU RS485) provided. 15- Compensating power factor able to be djusted:0.701ag ~ 0.70 forward.
