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
ETI0001-1250 is specifically designed for lightweightglobal power deployment or equally well in shallow depth racks. 

The heavy-duty chassis occupies only 7" (4U) of rack space while delivering up to 1550 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.

The internal shieldedinput transformer provides galvanic isolation with provisions forboth domestic (115 VAC, CONUS) and international (230 VAC, OCONUS) inputvoltages. The autoranging input 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. The inputswitch and the galvanic isolation transformer provide a double pole isolated source for all installations including shipboard systems oroverseas locations where phase references and grounding are not consistent. 

Alternately, theunit also accepts vehicular or aircraft power from nominal 24 VDC systems. The
ETI0001-1251 has the added benefit of having a front drawout hot-swappable battery module. 

The LED arrays keep the operator informed as to the unit's status including load and battery levels. The high intensity audible alarm canbe heard in high noise environments.All controls and protective devices are brought to front and rear panels with critical switches having finger guards. Further, all front panel devices are recessed to preventdamage or accidental operation. 

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. The batteries are maintenance free with immobilized electrolyte and are constructed of flame retardant materials. 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
ETI0001-1482 for a version of this UPS with an integrated PDU and remote control

Overall, the Military Power line is uniquelyqualified for critical shipboard, vehicle, airborne or land based systems combiningadvanced modular design features with highly reliable construction.
