Alpha Trans Co., Ltd. is a company primarily engaged in the design, development, and manufacturing of switching power supplies and transformers. Since its founding, veteran engineers have quickly mastered power supply ICs from various IC manufacturers, striving to develop switching power supplies that meet customer needs in terms of cost and functionality. We will continue to maintain this approach, swiftly capturing technological trends in the power supply industry, reflecting them in our design and development, and providing products that delight our customers. Regarding transformers for switching power supplies, we have received positive feedback for transformers that secure the distance between the primary and secondary using original bobbins. With the development of the SPT series, we will introduce a new series of bobbins. We will conduct further detailed examinations compared to the previous series, ensuring that our products will exceed your expectations.
