ETI0001-1237 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
ETI0001-1237 was specifically designed to mountin the TAC-4 racks and interface with either the TAC-4 PDU or any of numerous ETI PDUs. 

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 operator informed as to the unit's status including load and battery levels. The high intensity audible alarm canbe heard in high noise environments, yet is easily adjustable to suit quieter conditions.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.
