2- Product Selection
The GAIA Converter HGMM-350 designates a family
of non isolated AC/DC power factor corrected
modules. The HGMM-350 family is designed to
be compatible with the latest airborne single
phase input bus 115VAC/400Hz fixed and varia-
ble frequency and shipborne single phase input
bus 115VAC/60Hz.
The modules accept an AC input voltage ranging
from 95Vac to 140Vac and include active power
factor that enables a very low level of current
harmonic distorsion.
The HGMM-350 is compliant with numerous
avionics/military standards requirements among
them with :
• the latest Airbus standards ABD100 :
- permanent input range : 108-122Vac
- transient : 71Vac/15ms - 180Vac/100ms
- variable frequency : 360 - 800 Hz
- power factor : > 0,95
• the international standard DO-160D :
- permanent input range : 100-122Vac
- transient : up to 180Vac/100ms
• the US military standard MIL-STD-704E :
- permanent input range : 108-118Vac
- transient : 80Vac/10ms - 180Vac/100ms
• the US military standard MIL-STD-1399

Non Isolated Output
Metallic Case
The HGMM-350 modules include a soft start an
active inrush current limitation, a permanent
short circuit protection and an inhibit function.
The soft-start/active current limitation eliminates
inrush current during start-up, the short circuit
protection protects the module against short-
circuits of any duration by a shut down and
restores to normal when the overload is removed.
The HGMM-350 output voltage is set to 375Vdc
compatible with GAIA Converter high input vol-
tage series of DC/DC converter and operates
with a hold-up capacitance to allows transparency
time and ripple reduction.
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 metalic
case to ensure the module’s integrity under high
environmental conditions.
