AVIONICS / Defense Modular Power Architecture
Avionics and Defense power supplies have always been subjected to stringent requirements including transients, spikes, EMI, hold-up, monitoring specifications. As a result majority of power supplies have been designed specifically with discrete components.
Since the beginning of the 90’s with the introduction of the COTS (Commercial Off-The-Shelf) philosophy in US and modular power architecture the use of standard modules has become of more importance to design complex power supplies.
The most common standard input voltages in Avionics and Defense applications are 24, 28, 270 VDC or 115 VAC within a permanent variation of 16-40 VDC or 70-180 VAC to meet worldwide standards. Drop out down to 0VDC and transients have also to be covered. EMI compliance is of primarly importance and are described in the widely used MIL-STD-461 or DO-160 standards.

AC/DC Modular Power Architecture
To cope with these particular requirements, GAIA Converter proposes typical Off-The-Shelf modular power architecture :
- FGDS series : qualified front filters to allow compliance with MIL-STD-461 or DO-160 EMI requirements
- PGDS, LGDS series : essential functions such as drop-out voltage recovery, transient and spike protections as per MIL STD-704, MIL-STD-1275 or DO-160
- HGMS series : power factor corrected 115VAC to 28VDC converters allow easy board intermediate bus configurations
- HUGD series : monitoring and hold-up functions are provided by GAIA Converter hold-up module to sustain bus losses together with fault and advisory signals
- MGDM series : for the heart of the power system, GAIA Converter proposes a complete series of low profile, cost-effective and high performance DC/DC modules that come in multiple combinations of input voltages, output possibilities and power ratings
Whatever your power system´s need, GAIA Converter has a modular architecture using standard products to provide an instant solution to a wide range of applicationsfrom on-board computers, man-machine interface, communication systems, ...
