Additional
Ruggedization to meet MIL-STD-810: The
UPS System’s construction is extremely
robust, and ruggedized throughout. All components
and modules within the unit are mounted
using additional steel brackets and heavy-duty
stainless-steel hardware, which is then
further secured using Loctite and RTV where
required. All
boards are triple conformal-coated (Acrylic
MIL-I-46058 Type R) and mounted vertically
for maximum resistance to potential condensation
and fungus growth. For additional protection
against humidity, low-draw heating elements
are included within the unit, and drain
holes are placed strategically in the base
of the chassis to allow any formed condensation
to escape.
Internal
EMI Reduction Package to meet MIL-STD-461:
The design of this unit is specifically
focused on reducing EMI emissions. The UPS
contains substantial internal filtering
to minimize EMI emissions, including a very
large input filter rated for MIL-STD-461
CE03 applications and a hefty output filter
as well. Inputs which may be susceptible
to transients related to aircraft applications
are protected by several methods, including
MOVs. All internal magnetics are shielded
with copper and mu-metal to further minimize
emissions. The compact rack mount chassis
(7” High x 19” Wide x 22.25”
Deep) is specifically treated with low surface
resistivity finishes on the interior. All
aluminum parts are treated with clear irridite.
The steel parts are treated with zinc plate,
followed by a clear chromate. All exterior
portions (except for mating surfaces) are
then painted with glossy ANSI-61 gray to
assure excellent bonding of mating sheet
metal parts. All input and output ventilation
filters include metal honeycomb-style filters.
The results of these and other measures
provide a UPS System that complies to portions
of MIL-STD-461 by inherent design methods.
Super-Rugged,
Long Life Hawker Energy Batteries: Internal
Hawker Energy batteries provide over 5 minutes
back up time at full load. These batteries
are extremely resistant to shock, vibration,
and wide temperature ranges. Also, they
have a very long service life (8-10 years
measured at 25 degrees Celsius ambient temperature)
for a minimum of maintenance.
