Advantages
- Smaller than isolating transformers
- Input-output reverse operation possible
- High performance due to the heat dissipation achieved through special air vents
- Easy installation using special mounting supports that permit the comfortable use of tools
- Ergonomic and safe operation (IP20) due to design of metal enclosure
- Safe and simple cable connection achieved through use of special terminals and cross-connection fittings (IP20)
- Protection against contact with conductive parts (IP20)
- 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
Applications
- When one voltage must be converted to another and no galvanic isolation is required.
- To power USA devices (230V / 110V)
- To regulate the speed of single-phase motors (such as fans)
- In cases where the nature of the installation site requires protection against human contact and/or insertion of foreign objects (IP20)
