500 Watt Rugged DC NEMA UPS

ETI0005-1476 Standard NEMA Enclosure PowerStation™Isolated UPS
500 Watt Rugged NEMA, Modular Power System

The field proven PowerStation UPS line is ideally suited for military, industrial and telecommunications applications requiring rugged rack or table mount and/or portable construction, high reliability, compact size and light weight design. The heavy duty chassis occupies minimal space while delivering up to 500 Watts of clean, uninterruptible power. Internally, all major components are well secured and electrically insulated to prevent damage due to shock and vibration. An internal transformer bay accommodates the input isolation transformer with provisions for both domestic and optional international voltages for ratings up to 500 Watts. 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. Various optional power distribution controls are available which mount internally or remotely.

Locking connectors for the input and output power are available as options. Multiple input and output power panel options are also available. A washable intake air filter and high capacity ball bearing fan provide added protection in both controlled and hostile environments. The exhaust air is diverted out side vents. An external battery connector allows the safe and easy addition of extra battery modules without having to shut the unit down. A frequency selection switch is available for those sites requiring 50 hertz output instead of the standard 60 hertz. The status D shell connector provides signals to interface with optional computer software providing loss of AC and low battery status as well as remote shut down capability.

Overall, the PowerStation line is uniquely qualified for critical vehicle, industrial, shipboard, airborne or land based systems combining advanced modular design features with highly reliable construction.
