Gaia AC/DC Power Factor Corrected
Simplifying your future
AC/DC Power Factor Corrected Front-Ends
GAIA Converter’s AC/DC Power Factor Corrected (PFC) front-end modules are designed to deliver efficient and reliable AC to DC conversion in demanding environments. These modules integrate power factor correction to optimize energy efficiency and reduce harmonic distortion, ensuring compliance with stringent electrical standards. With options available for both low and high power needs, GAIA offers modules with dual isolated low-voltage outputs (under 50W) and non-isolated high-voltage outputs (above 150W), making them versatile for a wide range of system configurations.
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.
