For this project, a solution was sought for the unique American mains voltage (3x460V+N, 60Hz). Decalec designed a specially tailored transformer that converted this voltage to 3x400V+N, suitable for fan control. The project required precision and a thorough knowledge of local regulations. In addition, the transformer had to meet stringent safety and durability requirements. Thanks to our innovative design, the system now operates efficiently and trouble-free.
