Imagine your test equipment suddenly is ten times better than before

As the world attempts to move to a more and more green lifestyle, test solutions for battery powered systems and battery testing must meet various market demands such as highest power and energy density, durability, safety and energy efficiency.

Atos has developed the fully digital power supply “ProUSTuniverSAS®”, a new unique solution of highest efficiency, versatility and safety for the testing of batteries and battery powered subsystems. ProUST univerSAS® has been designed with several markets, like Aerospace, automotive and PV systems in mind.


Output efficiency of 95%, in sink mode the energy is fed back into the grid, instead of being converted into heat, making it a real green device
