1.Adopt AC sampling technology
2.Math integral,filter the wave,no sensitive to harmonic wave

1.General description

 RPCF series reactive power automatic compensation controller takes the 16-bit micriprocessor as its core,adopts Fourier series calculation method to get all the power data of fundamental wave, it is epecially suiitable for power system who has harmonic wave, applied to automatic control the reactive power compensation.All the elements adopt plaement installation, reflow soldering,multi channel checking,these advantages enable each piece of RPCF possess the same wonderful stability and reliability, RPCFC has RS485 interface, standard communication protocol, and it can be used as network meter.

 2.Features

1.Calculate switching capacitance by reactive power of fundamental wave, it can avoid switching shock of any forms, and display power factor of electric network when there exists the harmonic wave.

2.Measure power factor accurately, and with wide display rage.

3.Real-time display total power factor(PF)and fundamental wave power factor(DPF).

4.Real-time display voltage distortion factor and current distortion factor.

5.There are 12 types of coding output methods for users to choose.

6.Max output 16 ways.

7.conveniently operation between human and the machine through the interface.

8.All the control parameters are adjustable

9.With autiomatic operation and manual operation

10.With functions of over-voltage and under-voltage protection.

11.With protection function when voltage harmonic wave exceeds the standard.

12.With power-off protection function, the data will not lose

13.Input cument signal and the impedance is very low ≤0.01Ω

14.With communication function (MODBUS-RTU Rs485)

15.Wide power factor adjusting range,-0.70~+0.70
