GAIA Converter, the rugged power supplies specialist, has released a front-end hold-up module targeting Avionic and Military applications. The HUGD-300 is designed for applications that need to meet power hold up requirements in their designs, up to 300W. Such on-board applications need to remain operational between 50ms to 200 ms or more when an input voltage drop occurs. Doing so is traditionally done by using large bulk capacitors.
The first HUGD-300 function is to boost the capacitor charging voltage, using a user settable voltage from 30V to 80V, this drastically reduces the capacitor size up to a ratio of 10 to 1.
HUGD-300 module also has very low loss reverse polarity protection, input power bus monitoring, power fail, capacitor inrush current control and power hold-up monitoring. The HUGD-300 can be used with any GAIA Converter DC/DC modules to build complete power architectures up to 300W total power and provides monitoring signals optimised for global supervision. All these HUGD-300 features are packed into the compact and low profile industry standard 1”x1.5” module.
