General Description
The RPCF series automatic reactive power compensation controller, based on a 16-digit microprocessor, adopts Fourier series decompose arithmetic to get all power fundamental wave data. It is particularly suitable for the automatic control of reactive power compensation in the power system with harmonic wave source. All components are surface mounted. Then, they experience reflow soldering and multi-stage inspection. This enables all RPCF controllers to work steadily and reliably. In addition, this series of product has RS485 port and supports standard protocols. It can be used as a network meter.

Function Features
1. Calculating the switching capacitance according to the fundamental wave reactive power can avoid switching shock of any forms, and the power factor of the system with harmonic wave can be accurately displayed.
2. High measurement accuracy, wide display scope.
3. Real-time display of general power factor and fundamental wave PF.
4. Display the distortion rates of voltage and current in real time.
5. There are 12 kinds of coding output modes for selection.
6. 16 circuits of output at most.
7. Friendly interface, convenient to operate.
8. Various control parameters can be adjusted digitally.
9. Two operation modes: automatic operation and manual operation.
10. Excessive voltage harmonics protection function.
11. Overvoltage and undervoltage protection provided.
12. Data not lost even if power shut down.
13. Current signal input resistance ≤0.01Ω.
14. Communication function ((MODBUS-RTU RS485) provided.
15. A wide adjustment range of the targeted power factor: 0.70 lag~0.7 forward.
