  • The ECO transformer features high efficiency resulting in much lower losses than a standard transformer, resulting in an important reduction of the exploitation costs
  • The ECO transformer additionally offers important technical advantages:
    • Lower heat generation, reducing necessary cooling provisions in the area of installation
    • Longer lifetime thanks to reduction of thermal load on the isolation materials
    • Lower voltage drop, avoiding fluctuation in the output voltage
    • Suitable for higher ambient temperatures
    • Lower inrush current, avoiding tripping of devices at the moment of connection
    • Lower noise levels
