DPF6  Power factor controller 

Automatic power factor controllers with 6 relays, and microprocessor designed for signal processing of strongly distorted waveform to ensure accurate control of the electrical parameters of the plant. All measurements are made starting from the analysis of the waveform using FFT (Fast Fourier Transform) algorithm in floating point to ensure the maximum precision.

In addition to the normal power factor management functions, the device monitors the network and preserve the capacitor banks by disconnecting them in cases of high harmonic distortion or in case of mains voltage micro-interruptions or drops. The microprocessor management allows to distribute the insertion/disconnection of the capacitive banks extending the life time. The software allows to set each battery with the nominal value of the capacitor and also to set advanced functions such as:

  • Battery fixed (useful for fixed rephasing)
  • Temperature thresholds for ventilation control
  • Alarm relay setting
  • TA setting
  • Setting connection times and RC Time

The controller allows the following measurements to be monitored:

  • Power factor (inductive/capacitive)
  • RMS voltage
  • RMS Current
  • Missing power to reach set-pint (inductive, capacitive)
  • Active and reactive power
  • THDI
  • Temperature

The controller is equipped with RS485 serial interface with standard Modbus RTU communication protocol.*
