The field proven Rugged Systems™ UPS line is ideally suitedfor military, industrial and telecommunications applications requiring a ruggedrack, vehicular or field deployable, high reliability, compact size and lightweight design. The “1245” is being used guidance systems in harshenvironments because of the stringent performanceand reliability requirements. The heavy-duty chassis, occupying only 7.0” (4U) by14.0” depth, has rounded metal corners and rugged handles frontand rear, aiding in safe handling. Internally, all major components are wellsecured and electrically insulated to prevent damage due to shock andvibration. The internal EMI/RFI filters minimize input current harmonics. Toprovide added flexibility and reliability, the “1245” accepts two independenthot swappable Battery Modules. This system is designed to provide full outputfor 6 hours following an AC power outage even when the external temperature isbelow freezing. The LED arrays keep the operatorinformed as to the unit's status including load and battery levels. Allcontrols and protective devices are brought to the front panel. Further, all front panel devices areguarded toprevent damage or accidental operation. The input switch and the isolation provide double pole isolation for shipboard systems.
The rear panel provides locking connectors for the inputand output power. Removable and washable air filters and a high capacity ballbearing fan provide added protection in both controlled and hostileenvironments. The status connector provides an interface with optional computer softwareproviding loss of AC and low battery status as well as remote shut down capability.
Overall, the Rugged Power line is uniquely qualified for criticalshipboard, vehicle, airborne or land based systems combining advanced modular designfeatures with highly reliable construction.
