A small chamber for big projects: ACS test-bench DY110 C chamber contributes to the success of spatial missions thanks to DSI Aerospace GmbH testing activities

DSI Aerospace GmbH (DSI) is a medium-sized company headquartered in Bremen, Germany, that offers high-speed electronics for aerospace applications. Its activities focus on the design and development of solutions for computers, information technologies, control systems, and advanced communication systems.
Since its founding in 1997, DSI has established itself as a reliable partner for space agencies and system integrators, offering comprehensive and innovative solutions, including mass storage units, on-board computers, instrument control, and payload data handling units.

DSI specializes in the development of digital systems that enable significant savings in re-source requirements in terms of power consumption, weight, and volume. At the same time, the integrated approach ensures a significant increase in computing power and reliability through the use of the latest space-qualified hardware (FPGAs and ASICs).

DSI's customers include Airbus DS, OHB, the German Aerospace Centre (DLR), and the European Space Agency (ESA). The company is active in numerous national and international projects and participates in major ESA missions, including MetOp-SG, JUICE, Biomass, FLEX, PLATO, and Hera.

ACS test-bench DY110 C chamber is used, among other things, for testing commercial components to determine their suitability for use in space applications. Test criteria according to American and European standards are applied, for example, 1000 hours at 85°C and 85% RH, 500 temperature cycles from -55°C to +125°C, or 2000 hours at 125°C. During the tests, the components are functionally and parametrically tested via external electronics. The ACS chamber can simulate real-world environmental parameters in a temperature range of -65°C to +180°C. This temperature range is particularly well-suited for aerospace applications and all types of testing. The system enables high heating and cooling rates of up to 3K/min, which is a significant advantage, especially when temperature-changing with test specimens. In the low-temperature range, the chamber uses the most environmentally friendly low-temperature refrigerant on the market, R472 B, with a GWP of only 526.
