98V27004001001 is a high-stability aerospace DC-DC converter, engineered to AS9100D quality standards and RTCA DO-160G environmental specifications, designed 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 precise 12V DC output, delivering up to 10A current with ±0.3V voltage stability and <2% ripple. It integrates overcurrent, overvoltage, and thermal overload protection, plus temperature compensation for extreme conditions (-55°C to 125°C) and 20g vibration resistance. Weighing 0.35kg and measuring 75mm×50mm×30mm, it complies with FAA Part 25/EASA CS-25, ensuring uninterrupted power to navigation and communication subsystems, reducing avionics downtime, and boosting flight system reliability for commercial fleets.
