98V27004001000 is a high-efficiency aerospace DC-DC converter, engineered to AS9100D quality standards and RTCA DO-160G environmental specs, tailored for narrow-body aircraft like the Boeing 737 MAX and Airbus A320neo avionics systems during MRO and in-service operations.

Housed in an EMI-shielded, IP67-sealed aluminum enclosure, it converts unregulated 18–32V DC input to a stable 5V DC output, delivering up to 8A current with ±0.2V voltage precision and <1.5% output ripple. It integrates overcurrent, overvoltage, and thermal overload safeguards, plus temperature compensation for extreme flight conditions (-55°C to 125°C) and 20g vibration resistance. Weighing 0.3kg and measuring 70mm×48mm×28mm, it complies with FAA Part 25/EASA CS-25, ensuring uninterrupted power to critical avionics (e.g., navigation sensors, communication modules) and reducing unplanned MRO downtime for commercial fleets.
