1- General

The GAIA Converter limitor LGDS-300 is an ultracompact power adaptator module designed toallow operation during voltage transients and
spikes, occuring in avionics or military systems.
The LGDS-300 delivers an output voltage adapted
to GAIA Converter DC/DC modules. This moduleis optimized to provide high power efficiency upto 99% over the whole power range up to 300W.The LGDS-300 features 3 modes of operationsas follow:Օ Transient and spike operation : The LGDS-300 can sustain input transient upto 80V/100ms or 100V/50ms and spike up to
600V during 20յs with 50 ohms impedance .The LGDS-300 series is compliant with the inter-national input bus standards :- MIL-STD-704A/D/E/F
- AECMA EN2282
- GAM-EG13B/AIR2021E- DO160E cat A, B and Z- MIL-STD-1275A/B/C/DThe design has been carried out withsurface mount components and is manufactured
in a fully automated process to guarranty high
quality. Every module is tested with a Gaa
Converter automated test equipment. The mo-dules are potted with a bi-component thermalconductive compound and packaged in a metallic
case to ensure the modules integrity under
severe environmental conditions. Normal operation : Normal operation occurs in between the per-
manent input voltage of the DC/DC converter;The LGDS-300 is then operating in steadytransparency state. Power fail operation :The power fail operation occurs when theinput bus drops below 9 Vdc low voltage
limit ; an undervoltage lock-out stops the
LGDS-300. >
