Advantages


  • Ergonomic and safe operation due to the design of the metal enclosure
  • Safe and simple cable connection achieved through the use of special terminals and cross-connection fittings
  • Protection against contact with conductive parts
  • High performance due to the heat dissipation achieved through special air vents
  • Reliability achieved through high standards of quality control carried out by state-of-the-art, calibrated instruments at all stages of production, from receipt of raw materials to inspection of final products, one by one

Isolating transformers can be used:


  • Where galvanic isolation of the load and the user from the power source (e.g. power grid) is required for protective purposes. The supply voltage can be transformed to a different value at the same time
  • Where there is a need to supply large loads, such as in industry or shipping
  • In cases where the nature of the installation site requires protection against human contact and/or insertion of foreign objects

Safety isolating transformers can be used


  • When safe extra low voltage (SELV) is required, in addition to isolation
  • In auxiliary automation circuit power supply, when a high level of safety is required in handling
  • Where there is a need to supply large loads, such as in industry or shipping
  • In cases where the nature of the installation site requires protection against human contact and/or insertion of foreign objects
