The field proven Military Power® UPS line is ideally suited for military, industrial and telecommunications applications requiring a rugged rack, vehicular or field deployable, high reliability, compact size and light weight design. The
ETI0001-1255 is being used by the US Navy because of their stringent performance and reliability requirements.

The heavy-duty chassis, occupying only 7” (4U) of rack space and 18.5” depth, has rounded metal corners and rugged handles front and rear, aiding in safe handling. The front panel is water proof meeting the Mil Standards for water dripping onto the front panels. Internally, all major components are well secured and electrically insulated to prevent damage due to shock and vibration. The internal shielded input isolation transformer, EMI/RFI filters and input power factor correction minimize both input current and harmonics. The unit also operates as a frequency converter, taking 46-440 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. All controls and protective devices are brought to the front panel with critical switches having finger guards. Further, all front panel devices are recessed to prevent damage or accidental operation. The input switch and the isolation transformer provide double pole isolation for shipboard systems.

The rear panel provides locking connectors for the input and outputpower. Multipleinput and output power panel options are available. Removable and washable air filters and a high capacity stainless steel ball bearing fans provideadded protection in both controlled and hostile environments. The exhaust air is diverted out the frontvent, with alternateair flow directions optional. The
ETI0001-1255 has the added benefit of having afield replaceable battery via a rear drawout battery module. The batteries are maintenance free with immobilized electrolyte and are constructed of flame retardant materials.
