The DCRG automatic power factor controller satisfies the technical requirements of modern electrical systems in industry. It is designed to satisfy them, with the option of extending its functionality by using specific EXP series expansion modules. Mention should also be made of the optical communication port as standard, for programming the controller, diagnostics and data download. The backlit graphic LCD facilitates data reading even in poor lighting conditions and permits the display of system information clearly and intuitively.

  • Main Features:
    – 128×80 pixel backlit graphic LCD display with texts in ten languages: Italian, English, Spanish, French, German, Czech, Polish, Russian, Portuguese and one customisable.
    – Connection in single and three phase lines as well as three phase lines with neutral control and co-generation systems (four quadrant).
    – Capacitive reactive power factor correction (DCRG 8IND).
    – Independent power factor correction for each individual phase (SPPFC).
    – Use with medium voltage lines with VTs.
    – Capability for correct operation even in systems characterised by high harmonic content.
    – Drastic reduction in the number of switching operations.
    – Balanced use of steps with same power rating.
