ETI0001-2250AB Rugged Mil Spec UPS Standard Rear Panel Layout

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, fielddeployed or fixed locations with controlled or uncontrolled environments.The
ETI0001-2250AB was specifically designed to mountin the TAC-4 racks and interface with either the TAC-4 PDU or any of numerous ETIPDUs. 

The heavy-duty chassis occupies only 5.25" (3U) of rack space while delivering up to2000 VA of clean, uninterruptible power. The rounded metal corners and rugged handles, aidin safe handling. Internally, all major components are well secured and electricallyinsulated to prevent damage due to shock and vibration. The optional heavy-duty rack slides provideeasy installation and removal of the unit with full extension. Rear shockisolation/alignment bushings off load the slides when the unit is fully engaged.

The internal shielded input transformerprovides galvanic isolation with provisions for both domestic(115 VAC, CONUS) and international (230 VAC, OCONUS) input voltages. Theinput voltage selection allows inputting either 115 VAC or 230 VAC without having to open the UPS enclosure. Special EMI/RFI filters and input power factor correction minimize both input current and harmonics. Theunit also operates as a frequency converter, taking 46-70 hertz input and converting it to clean, uninterruptible 60 hertz power. Optionally, 46-440hertz input as well either 50or 400 hertz outputs are available. 

The LED arrays keep the operatorinformed 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 front panel also provides easy access to both the AC Input and Battery Input fuses. Coupled with the adjacent spare fuses, MTTR is reduced to less than 15 minutes.

The internal intelligent thermalsensors provide two stage monitoring of unit temperatures,with both local andremote Battleshort override capability of thermal shutdown. Battleshort can beengaged via the front panel control, via a remote contact input or via asoftware command. When in Battleshort, an audible alarm is sounded and anindicator is lit. Thehigh intensity audible alarm can be heard in high noise environments andincludes an audible enable/disable switch. 

All controls and protective devices are brought to the front and rear panels with critical switches or circuit breakers having finger guards. Further, all front panel devices are recessed to prevent damage or accidental operation. 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 rear panel provides locking connectors for the input and output power with various optional configurations available. This reverse air flow version draws air through the front and exhausts out the rearvent into the rack. A removable and washable intake air filter and high capacity stainless steel ballbearing fan provide added protection in both controlled and hostile environments. Clips on the rear panel hold additional spare fuses for ready access.

The
ETI0001-2250AB has the added benefit of having a field replaceable battery via front drawout battery module. The battery is a true hot-swappable module and does not require going to bypass like competing units. Even with this battery module 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 Battery Technology section. 

The two status D shell connectors provide both a contact and serial interface with optional computer software providing loss of AC and low battery status as well as remote shut down capability. See the Power Distribution Units section for a listing of stand alone PDUs. See the N5 Series
ETI0001-1437 for a version of this UPS with an integrated PDU and remote control.
