The Lone Star Aviation 14–28 VDC Step-Up Converter is a compact and reliable power conversion unit designed to provide a regulated 28 VDC output from a 14 VDC aircraft electrical system. It enables the operation of 28-volt avionics and accessories in aircraft equipped with a 14-volt electrical architecture.
Engineered specifically for aviation applications, this step-up converter delivers stable voltage conversion while meeting the reliability and performance expectations required for installed aircraft equipment. It is commonly used when upgrading avionics, installing 28 VDC accessories, or integrating systems that require a higher operating voltage than the aircraft’s primary power supply.
The LS03-05002-B is suitable for approved installations where a certified or manufacturer-approved voltage conversion solution is required, making it a practical choice for both retrofit and new avionics installations.
