Output
The GAIA Converter limitor LGDS-300 is an ultra
compact power adaptator module designed to
allow 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 module
is optimized to provide high power efficiency up
to 99% over the whole power range up to 300W.
The LGDS-300 features 3 modes of operations
as follow:
• Normal operation :
Normal operation occurs in between the per-
manent input voltage of the DC/DC converter;
The LGDS-300 is then operating in steady
transparency state.
• Power fail operation :
The power fail operation occurs when the
input bus drops below 9 Vdc low voltage
limit ; an undervoltage lock-out stops the
LGDS-300.
Transient
O : 100V/50ms
• Transient operation :
The LGDS-300 clamps input transient up
to 80V/100ms or 100V/50ms.
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/D
The design has been carried out with
surface mount components and is manufactured
in a fully automated process to guarranty high
quality. Every module is tested with a Gaïa
Converter automated test equipment. The mo-
dules are potted with a bi-component thermal
conductive compound and packaged in a metallic
case to ensure the module’s integrity under
severe environmental conditions.
