Automatic Power Factor Controller with Microprocessor Management, featuring 6/12 steps, designed for processing highly distorted waveform signals to ensure precise control of electrical parameters in the system.
All measurements are made starting from waveform analysis using the Floating Point Fast Fourier Transform (FFT) algorithm to guarantee maximum accuracy.
In addition to the standard power factor management functions, the device monitors the grid and safeguards capacitor banks by disconnecting them in the event of high harmonic distortion, micro-interruptions, or excessively low grid voltage. Microprocessor management allows for the distributed connection of capacitor banks, extending their lifespan. It also allows for the setting of the following advanced functions for each capacitor bank:
- Fixed battery (useful for fixed power factor correction)
- Temperature thresholds for ventilation control
- Alarm relay settings
- CT settings
- Connection times and RC Time settings
The controller can monitor the following measurements:
- Power factor (inductive/capacitive)
- RMS voltage
- RMS current
- Missing power to reach the set-point (inductive, capacitive)
- Active and reactive power THDI
- Temperature
The controller is equipped with an RS485 serial interface with the standard Modbus RTU communication protocol.*
