*It’s not referred to applications of motor’s starting
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 testing 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 three-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)
