The field proven Military Power® UPS line is ideally suited for military, industrial, computer and telecommunications applications requiring high reliability, rugged construction, compact size and light weight design. These units are equally suited for use in shipboard, airborne, vehicular, field deployed or fixed locations with controlled or uncontrolled environments. The ETI0001-1482 was specifically designed for US Navy Submarine systems requiring high density power in shallow depth racks. The ETI0001-1482 does not require a separate PDU since the PDU functions are already integrated into the UPS module. This saves rack space, cabling and expense while improving overall reliability.
The heavy-duty chassis occupies only 4U (7.0”) of rack space and is only 18.5″ deep making it suitable for shallow racks as found on submarines. The front panel is sealed meeting the Navy drip proof requirements. The rounded metal corners and rugged handles, both front and rear, aid in safe handling. Internally, all major components are well secured and electrically insulated to prevent damage due to shock and vibration in any axis. These units can be mounted horizontally or vertically.
The internal shielded input transformer provides galvanic isolation with provisions for both domestic(115 VAC, CONUS) and optional auto-ranging international input voltages (85-270 VAC,OCONUS). The unit also operates as a frequency converter, taking 46-70 hertz input and converting it to 60 hertz power. Special EMI/RFI filters and input power factor correction minimize both input current and harmonics. The input circuit breaker and the galvanic isolation transformer all provide a double pole isolated source for all installations including shipboard systems or overseas locations where phase references and grounding are not consistent.
The LED arrays keep the operator informed as to the unit’s status including load and battery levels. The Elapsed Time Indicator records the number of operational hours for records and scheduling preventative maintenance of attached equipment. The high intensity audible alarm can be heard in high noise environments. All controls and protective devices are brought to the front and rear panels with critical switches or breakers guarded. Further, all front panel devices are recessed to prevent damage or accidental operation. The internal intelligent PDU allows control of the individual output circuits incorporating thermal and interlock interfaces for additional control and safety, plus Battle-short override. The display and control panel can be mounted remotely in the rack at eye level, or on the keyboard console with only a logic level cable connection.
The rear panel provides locking connectors for the input and output power with various optional configurations available. The output connectors are unique allowing the use of either standard NEMA 5-15P plugs or MS threaded metal shell connectors. This unit draws air through the rear air filter and exhausts out the side vents into the rack. This allows the unit to be used in either positive, negative or neutral pressure racks. The removable and washable metal screen air filters and high capacity stainless steel ball bearing fans provide added protection in both controlled and hostile environments. The
ETI0001-1482 has the added benefit of having afield replaceable battery via a rear draw-out battery module. The batteries are maintenance free with immobilized electrolyte and are constructed of flame retardant materials.
For more information, see the Battery Technology section. The Status connector provides an interface with optional computer software providing loss of AC and low battery status as well as remote shut down capability.

Overall, the Outdoor Rugged Power line is uniquely qualified for critical shipboard, vehicle, airborne or land based systems combining advanced modular design features with highly reliable construction.
