AC/DC Power Factor Corrected Front-Ends
GAIA Converter’s AC/DC power-factor corrected front-end modules are DO-160, ABD-100, and Mil-Std-704 compliant. They are compatible with common airborne AC input bus voltages and variable frequencies.
They are particularly adapted to centralized power architectures in conjunction with PoL or isolated DC modules.
GAIA Converter’s AC/DC front-end modules have a soft-start, active current limitation, short circuit protection, and inhibit function. The soft-start/active current limitation prevents inrush current during start-up. The short circuit protection safeguards the module against short circuits by shutting down and restoring to normal when the overload is removed.
GAIA Converter’s products under 50W offer two isolated low voltage outputs. Products above 150W provide non-isolated high voltage output.
