This rugged Navy Galaxy-Series UPS System is specifically designed for submarine and shipboard applications in compliance to MIL-STD-1399, MIL-STD-461, MIL-STD-901,MIL-STD-810, AND MIL-STD-740. The example pictured is a compact 5 KVA unit built for use on the US Virginia Class Submarine, as well as other high profile shipboard and submarine applications in US and US-friendly fleets worldwide. This model has a three-phase power factor corrected (PFC) input of 115 VAC L-L, 50/60 Hz per MIL-STD-1399 Section 300 Type I and a pure sinewave galvanically isolated output of 115 VAC, Single-Phase. Single-phase input is optional, and output frequency is available in 50, 60, or 400 Hz (specify.) This UPS System contains all of the features standard on other Galaxy-Series units, as well as additional features that make it ideal for Naval applications.

SYSTEM COMPLIANCE

Additional Ruggedization to meet MIL-STD-901, IEC 68-2-6, and 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 conformal-coated (Acrylic MIL-I-46058 Type R) for maximum resistance to potential condensation and fungus growth. The unit was tested and qualified as follows:

MIL-STD-901C for Grade A, Class II Equipment: Shock test with half sinewave, 20ms duration, 15g peak acceleration shock pulse.

IEC 68-2-6 for Type I Testing: Between 3-10 Hz amplitude to be 0.5mm. Between 10-50Hz acceleration to be 2 m/s2

MIL-STD-810D: Operating Temperature Tests including High Temperature Test per Procedure II, Method 501.2, Table 501.2-II Ambient Air, 4 Cycles @ 24 Hours per cycle, Low Temperature Test per Procedure II, Method 505.2, Table 505.2-I Region CO, 4 Cycles @ 24 Hours per cycle, and Temperature Shock Test per Procedure I, Method 503.2, between 0-40 degrees Celsius, 4 Cycles @ 24 Hours per cycle.

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. Inputs which may be susceptible to transients 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 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 unit was tested and qualified as follows:

MIL-STD-461B Part VI for EMI Class A5: CE01, CE03, CS01, CS02, CS06, CS09, RE01, RE02, RS01, RS02, RS03.

Super-Rugged, Long Life Hawker Energy Batteries: External Hawker Energy sealed, maintenance free batteries provide 10 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. The batteries are user replaceable.

Structureborne and Airborne Noise: The rugged Navy Galaxy-Series UPS System was tested and qualified to MIL-STD-740B for Grade A Type III Equipment.

Pressure Tests for Submarine Usage: The Navy Galaxy Series UPS System was tested to atmospheric pressure within the range of 750-1250 millibars, and maintained standard operation to specification to the following test pressures for 1 hour:
250 millibars above ambient (applied within 30 seconds and released within 30 seconds)
250 millibars below ambient (applied within 30 seconds and released within 30 seconds)
Ambient pressure of 1000 millibars
