The field-proven Rugged Systems™ UPS line is ideally suited for military, industrial, computer and telecommunications applications requiring high reliability, rugged construction, compact size, and lightweight design. These units are equally suited for use in shipboard, airborne, vehicular, field deployed or fixed locations with controlled or uncontrolled environments. The”N5 Series” was specifically designed to save rack space and installation costs while enhancing the functionality of both the UPS and PDU. The “N5 Series” does not require a separate PDU since the PDU functions are already integrated into the UPS module. This saves rack space, cabling and expense while improving overall reliability.
The heavy-duty chassis occupies only 3U (5.25″) of Rackspace while delivering up to 2400 VA of clean, uninterruptible power. The rounded metal corners and rugged handles, both front and rear, aid in safe handling. The optional mounting kits include flanges that allow the use of TAC-4 style shock isolation pins and bushings used in some racks.
The internal shielded input transformer provides galvanic isolation with provisions for domestic (115VAC, CONUS) and optionally for international (230 VAC, OCONUS) input voltages. Special EMI/RFI filters and input power factor correction minimize both input current and harmonics. This unique circuit allows this UPS to deliver up to 20 amps to the load, while utilizing less than 20 amps from the source, thus maximizing the use of existing circuits.
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 the front and rear panels with critical switches or breakers guarded. Further, all front panel devices are recessed to prevent damage or accidental operation. Various optional power distribution controls are available which mount on the front panel or remotely.
The internal intelligent PDU allows control of the individual output circuits incorporating thermal and interlock interfaces for additional control and safety, plus Battleshort override. The display and control panel can be mounted remotely in the rack or on the front panel with only a logic-level cable connection. The input circuit breaker and the galvanic isolation transformer 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. Multiple input and output power panel options are available. 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 air is drawn from the rear and exhaust air is diverted out the front vent, 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 electrolytes and are constructed of flame retardant materials. For more information, see the Battery Technology section. The unit also operates as a frequency converter, taking 46-70 hertz input and converting it to 60 hertz power. A frequency selection switch is available for those sites requiring 50 hertz output instead of the standard 60 hertz. 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.
Overall, the Rugged Power line is uniquely qualified for critical shipboard, vehicle, airborne or land based systems combining advanced modular design features with highly reliable construction
