The field proven Rugged Systems™ 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 “ETI0001-1447” was specifically designed to meet the stringent requirements of the US Navy AN/SQQ89 (V)15 program. The “ETI0001-1447” 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 3U (5.25”) of rack space while delivering up to 2000 VA of clean, uninterruptible power. 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.
The internal shielded input transformer provides galvanic isolation with provisions for both domestic(115 VAC, CONUS) and optional auto-ranging international input voltages (230 VAC,OCONUS). Special EMI/RFI filters and input power factor correction minimize both input current and harmonics. The input switch 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 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, or on the unit front panel with only a logic level cable connection. This panel is also equipped with the EPO (Emergency Power Off) feature. EPO requires pressing two switches at opposite ends of the panel to avoid accidental operation. EPO will trip the input circuit breaker on the front of the UPS, removing all power from the unit and the loads.
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 reverse air flow version draws air through the front and exhausts out the rear vent into the rack. A removable and washable intake air filter and high capacity stainless steel ball bearing fan provide added protection in both controlled and hostile environments. 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.
