Power fail operation :An undervoltage lock-out stops operation and
disables the boost˻ mode for voltage below Transient suppressor module 80VՕ MIL-STD-704A/D/E/F, EN2282, AIR2021E DO160D cat A, B and ZՕ Transient suppressor module 100V MIL-STD-1275A/B,Օ Spike suppressor module 600V MIL-STD-704A/D/E/F, EN2282, AIR2021E
Օ DO160D cat A, B and Z Extended operation for voltage drop out and cranking down to 6VՕ Power range : from 4W to 50W
Inhibition function Low line operation :Low line operation occurs when the input
bus voltage drops down below the perma-
nent input voltage range of the DC/DC
converter ; then the PGDS-50 operates in
իboost mode to provide an output voltage
compatible with DC/DC converter.
The PGDS-50 series can sustain low line
operation down to 6V.

1- General

The PGDS-50 can sustain input transient up
to 80V/100ms or 100V/50ms and spike up to
600V during 20s with 50 ohms impedance .The PGDS-50 series is compliant with the inter-national input bus standards :- MIL-STD-704A/D/E/F
- AECMA EN2282
- GAM-EG13B/AIR2021E
- DO160D cat A, B and Z
- MIL-STD-1275A/BThe 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 Gaկa
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 modules integrity under high
environmental conditions. Normal operation : The GAIA Converter pre-regulator PGDS-50 seriesdesignates a low profile power adaptator mo-
dule designed to extend input bus voltage to
meet system operation during voltage transients,
spikes, cranking and drop out occuring in avionics
or military systems.
The PGDS-50 delivers an output voltage adapted
to GAIA Converter DC/DC modules. This line of
module is optimized to provide high power
efficiency up to 96% over the whole power range
between 4W and 50W.The PGDS-50 features 4 modes of operations asfollow:ҕ this low line operation.
Normal operation occurs between the per-
manent input voltage of DC/DC converter;
The module is then operating in steady
transparency state.
