Rail & Transportation

Designed to work under demanding conditions

We manufacture robust and highly reliable products that meet the demanding regulations and standards of the transportation and rail sectors offering a long life of the solution.

Efficient and reliable rail solutions

At Premium PSU we have designed and manufactured an extensive range of energy conversion solutions for the transportation market and specifically in railway applications for over 40 years. Our solutions are designed to work under demanding environmental conditions. All our processes, from design to testing and manufacturing, are carried out in Barcelona.

Our know-how allows us to offer solutions that cover very diverse applications within the railway sector. We work with worldwide manufacturers and suppliers of transportation systems since 1985, which places us as a trusted technological partner.

We have a standard range of converters, inverters and power supplies that comply with regulations and we develop custom made products according to the needs of each application regardless of the size of the project. Our knowledge base allows us to develop a product from scratch, reducing costs and delivery times.

We guarantee quality from the design and throughout the manufacturing process with the most advanced testing systems.
