The heavy-duty chassis occupies only 5.25″ (3U) of rack space while delivering up to 2000 VA of clean, uninterruptible power. The rounded metal corners and rugged handles, aid in safe handling. Internally, all major components are well secured and electrically insulated to prevent damage due to shock and vibration. The optional heavy-duty rack slides provide easy installation and removal of the unit with full extension. Rear shock isolation/alignment bushings off load the slides when the unit is fully engaged.

The internal shielded input transformer provides galvanic isolation with provisions for both domestic(115 VAC, CONUS) and international (230 VAC, OCONUS) input voltages. The 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 unit also operates as a frequency converter, taking 46-70 hertz input and converting it to clean, uninterruptible 60 hertz power. Optionally, 46-440 hertz input as well either 50 or 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 can be 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 prevent damage 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 rear vent into the rack. A removable and washable intake air filter and high capacity stainless steel ball bearing 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.
