Extreme Environments

Maximum optimization for the most strict and demanding market

We are aware of the role of an energy conversion system in equipment that has to work intensively in hostile environments, so we optimize our solutions to the maximum to meet the most demanding specifications and standards.


We oversee and take control over all processes from the design to the final solution, both in standard And in custom made products.

All products for use in extreme environment applications are tested with the most advanced testing systems in our facilities in Barcelona, where we are also able to adapt our production to the needs of each project.


At Premium PSU we have been designing robust power conversion systems for over 40 years.

Hi-Rel converters, inverters, UPS and power supplies for applications such as communication devices, land transport or surveillance systems.
