Part Number: ETI0001-2205A3 
Rugged MilSpec 5000 VA UPS
120 VAC Power Source with
3-Phase Input and 1-Phase Output

The heavy-duty UPS and Battery chasses have rounded metal corners and rugged handles front and rear, aiding in safe handling. Internally, all major components are well secured and electrically insulated to prevent damage due to shock and vibration.  The internal intelligent thermal sensors provide monitoring of unit temperatures, with both local and remote Battleshort override capability of thermal shutdown for emergency scenarios. Battleshort can be engaged via a remote contact input or via a software command. When in Battleshort, an audible alarm is sounded and an indicator is lit. The high intensity audible alarm can be heard in high noise environments and includes an audible enable/disable switch. 

The internal shielded input transformer provides galvanic isolation with provisions for nominal 208 VAC, 3-phase input voltages. Special EMI/RFI filters, input power factor correction and inrush current limiting minimize both input current and harmonics.

The unit can also operate as a frequency converter, taking 46-70 hertz input and converting it to clean, uninterruptible 60 hertz power.

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 having finger guards. The front panel also provides easy access to both the AC Input and Battery Input fuses. Coupled with the onboard spare fuses, MTTR is reduced to less than 15 minutes. Further, all front panel devices are recessed to prevent damage or accidental operation. The input circuit breaker and the galvanic isolation transformers 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. Removable, washable air filters combined with high capacity stainless steel ball bearing fans provide added protection in both controlled and hostile environments. The exhaust air is diverted out the rear vents, with alternate air flow directions optional. The external battery connector allows the safe and easy addition of the standard or extra battery modules without having to shut the unit down. 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.

See ETI0001-2205A3AA for a newer upgraded version of this unit that is totally backward compatible. See the Power Distribution Units section for a listing of stand alone PDUs. See the N5 Series section for versions of UPS with an integrated PDU and remote control.

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