Low power consumption and optimized thermal management are critical advancements for space or vacuum applications. The company’s PR4 U.2 and E1.S models consume <7.5W at 3GB/s and <1W at idle, over 50% less than other market solutions. This allows for maximal power allocation to scientific instruments and payloads, ultimately enhancing mission efficiency. Reduced power consumption also mitigates heat generation, vital for missions where heat dissipation is challenging. Enhanced thermal management ensures component reliability in extreme conditions, crucial for prolonged space exploration and research.

Durability and security features
