The field proven Extreme UPS® line is ideally suited for industrial, military, computer and telecommunications applications requiring high reliability, rugged construction, compact size and light weight design. These units are equally suited for use in locations with controlled or uncontrolled environments including fixed, field deployed, vehicular, shipboard or airborne.  For example, thousands of "ETI0001-2275" units are being used in the switchgear of wind turbine generators around the world. In this application, the output supports both a computer type load and operates large inductive switchgear contactors at the same time. This places extreme demands in electrical performance that causes most other vendors' UPS products to fail. In the case of the ETI0001-2275, it is able to provide the large surge currents required to operate the contactors without dropping the voltage and loosing the computer load!! On top of this, the equipment operates in harsh temperature environment ranging from as low as -40° Fahrenheit (-40° Celsius) to as high as 149° Fahrenheit (65° Celsius).

The heavy-duty chassis, occupying minimal space while delivering up to 2000 VA of clean, uninterruptible power. The rounded metal corners and rugged handles, aid in safe handling. Internally, all major components are well secured and electrically insulated to prevent damage due to shock and vibration.  These units can be mounted horizontally or vertically. Optional heavy-duty rack slides provide easy installation and removal of the unit with full extension.

The internal shielded input transformer provides galvanic isolation with provisions for both domestic (115 VAC, CONUS) and international (230 VAC, OCONUS) input voltages. The optional autoranging input voltage selection allows inputting either 115 VAC or 230 VAC without having to open the UPS enclosure. These units work equally well from all AC sources including poorly regulated generators. Special EMI/RFI filters and input power factor correction minimize both input current and harmonics.  The unit also operates as a frequency converter, taking 46-70 hertz input and converting it to clean, uninterruptible 60 hertz power. The input switch and the galvanic isolation transformer all provide a double pole isolated source for shipboard systems or overseas locations where phase references and grounding are not always consistent. The nominal 120 VAC, 60 hertz output can be field set for 100, 110 or 115 VAC. An alternate version is also available for 200-240 VAC, 50 hertz output. 

All controls and protective devices are brought to the outer panels with critical switches or circuit breakers having finger guards. Further, all critical devices have finger guards to prevent damage or accidental operation. 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. The internal intelligent thermal sensors provide monitoring of unit temperatures. The optional Elapsed Time Indicator records the number of operational hours for records and scheduling preventative maintenance of attached equipment. The front panel also provides easy access to both the AC Input circuit breaker and Battery Input fuse. Coupled with the onboard spare fuse, MTTR is reduced to less than 15 minutes.

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 manual bypass feature included is operated from the front panel. Even in the bypass mode, the ETI0001-2275 still provides galvanic isolation, transient surge protection and EMI/RFI filtering. The unit also has a self test feature that can be initiated by the operator from the front panel.

The ETI0001-2275 has the added benefit of having a field replaceable battery tray. Even with this battery tray removed, this UPS can continue to operate as an electronic power conditioner and frequency converter, providing clean, well regulated, sinusoidal power to the load. The batteries are maintenance free with immobilized electrolyte and are constructed of flame retardant materials for added safety. For more information, see the
