Front end hold-up module can handle up to 300W

The HUGD-300 can handle up to 300W and is designed for applications that need to meet stringent power hold-up requirements in their designs. Traditionally, such on board applications use large bulk capacitors to sustain a hold-up time of between 50 and 200ms or more following a voltage drop in order to save critical data. The first function of the HUGD-300 is to boost the capacitor charging voltage. Using a user settable voltage of 30 to 70V allows the capacitor size to be reduced by up to 90%. This also helps the HUGD-300 achieve a compact, industry standard overall footprint of just 40.8 x 27mm with a low profile of 12.7mm, helping to further ease its integration into space constrained designs. Also incorporated in the HUGD-300 module are functions such as low loss reverse polarity protection, input power bus monitoring, power fail, capacitor inrush current control and power hold up monitoring. The new modules can be used with any Gaia Converter dc/dc modules to build complete power architectures up to 300W total power and provide monitoring signals optimised for global supervision. The HUGD-300 can also be connected to two input bus networks with a fast transition in the case of one bus power failure.
