HGMB-50-W-17 – New Gaia 50 W PFC module for avionics industry

The Gaia Converter HGMB-50-W-17 active power factor corrected AC-DC isolated module  is designed to be compatible with the latest airborne input bus with single-phase 115VAC/400Hz variable frequency.  Gaia’s HGMB-50 High-Reliability AC-DC PFC is designed for higher operating temperatures of -40 to +105°C (optional -55°C) for typical military & airborne applications:

The HGMB-50 comes with 2 isolated 17 Vdc outputs which can be connected in series for a  34 Vdc output, or paralleled or kept independent.

The HGMM-50 includes a soft start, a permanent short circuit protection and an inhibit function. The soft-start allows current limitation and eliminates inrush current during start-up. The short circuit protection completely protects the module against short-circuits of any duration by a shut down and restores to normal when the overload is removed.

The HGMB-50 is compliant with numerous avionics/military standards:

 Airbus standards ABD100 :
   • permanent input range : 108-122 Vac
   • transient : 71 Vac/15 ms – 180 Vac/100 ms
   • variable frequency : 360 – 800 Hz
   • power factor : > 0,95

International standard DO-160E/F/G :
   • permanent input range : 100-122 Vac
   • transient : up to 180 Vac/100 ms

US military standard MIL-STD-704E/F :
   • permanent input range : 108-118 Vac
   • transient : 80Vac/10 ms – 180Vac/100 ms
