Series Description
The GAIA Converter HGMM-350 designates a family of non isolated AC/DC power factor correctedmodules. The HGMM-350 family is designed tobe compatible with the latest airborne singlephase input bus 115 Vac / 400 Hz fixed and variable frequency and shipborne single phase inputbus 115 Vac / 60 Hz.
The modules accept an AC input voltage rangingfrom 95 Vac to 140 Vac and include active powerfactor that enables a very low level of currentharmonic distorsion.
The HGMM-350 is compliant with numerousavionics/military standards requirements among them with: 
- the latest Airbus standards ABD100: 
. permanent input range : 108-122 Vac 
. transient : 71Vac/15ms - 180Vac/100ms 
. variable frequency : 360 - 800 Hz 
. power factor : 0,95 
- the international standard DO-160D: 
. permanent input range : 100-122 Vac
. transient : up to 180Vac/100ms 
- the US military standard MIL-STD-704E: 
. permanent input range : 108-118 Vac
. transient : 80Vac/10ms - 180Vac/100ms 
- the US military standard MIL-STD-1399. 
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 375 Vdc compatible with GAIA Converter high input voltage series of  DC/DC converter and operates with a hold-up capacitance to allows transparencytime 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 GAIA Converter automated test equipment. The modules 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.
