98V27004000001 is a high-reliability aerospace voltage regulation module, engineered to AS9100D quality standards and RTCA DO-160G specifications, tailored for narrow-body aircraft (Boeing 737 MAX, Airbus A320neo) electrical systems. It stabilizes fluctuating input voltage (110–240V AC) into a consistent 28V DC output, powering critical avionics components such as navigation sensors, communication transceivers, and flight control modules.

Constructed from lightweight aerospace-grade aluminum alloy with IP65 sealing, it operates stably across -55°C to 125°C, resists vibration up to 25g, and features over-voltage/over-current protection circuits. Weighing 1.1kg with compact rack-mount dimensions, it integrates seamlessly into aircraft electrical bays. FAA Part 25/EASA compliant, it minimizes power supply interference and upholds electrical system integrity for commercial fleets.
