The field proven Rugged Systems™ Power Distribution Unit (PDU) line is ideally suited for military, industrial and telecommunicationsapplications requiring a rugged rack, vehicular or field deployable, high reliability, compact sizeand light weight design. The heavy-duty chassis occupies only 1U (1.75”) ofrack space while controlling up to 2400 VA of power via six double polecontrols. Therounded metal corners and rugged handles aid in safehandling. Internally, all major components are well secured and electricallyinsulated to prevent damage due to shock and vibration. All controlsand protective devices are brought to the front panel with critical switches orbreakers guarded. Further, all front panel devices are recessed to preventdamage or accidental operation. The control panel contains individual controlbreakers, alarm silenceswitch and alarm LEDs.

The LEDarrays keep the operator informed as to the unit's status. An alarm will flashits respective LED until acknowledged. Once the alarm reset is pressed, the LEDwill remain on steady until the alarm is cleared. The intelligent PDU allows control ofthe individual output circuits incorporating thermal and interlock interfacesfor additional control and safety, plus Battleshort override. Each loadcan have an external interlock toturn off power to equipment when it is not fully engaged in the rack or becomesoverheated. The rack may be equipped with both a thermal warning and a thermal shutdown sensor that thePDU uses to alarm and shut down all the loads to avoid damage or thermalrunaway. A Battleshort signalwill override both the thermal and interlock signals. An external Fan Fail orauxiliaryalarm signal can also brought in to annunciate. The high intensity audible alarm can be heard in high noiseenvironments, yet is easily adjustable to suit quieter conditions. The double pole inputbreaker provides overload and short circuit protection for the connected UPS inputisolation transformer and rack fans. The PDU input circuit breaker on/off operation is also interlocked to control the UPS on/offfunction as well. Power from the UPS is brought back to the PDU to bedistributed to the loads. Eachload is controlled and protected by both a double pole shock rated circuitbreaker and by a double pole solidstate relay

Therear panel provides locking connectors for the input power, output power, alarmand control signals. Appropriate jumper plugs are available for options notused in a particular rack system.

Overall, the Rugged Power product line is uniquely qualified for critical shipboard,vehicle, airborne or land based systems combining advanced modular designfeatures with highly reliable construction.
