The heavy duty chassis occupy only 3U of rack space while delivering up to 1550 VA of clean, uninterruptible power. The rounded metal corners and rugged handles, both front and rear, aid in safe handling. The optional mounting kit includes flanges and legs for either horizontal or vertical positioning. 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. 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 panel with critical switches or breakers guarded. Further, all front panel devices are recessed to prevent damage or accidental operation.

The internal intelligent PDU allows control of the individual output circuits incorporating thermal and interlock interfaces for additional control and safety, plus Battle short 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. A washable intake air filter and high capacity stainless steel ball bearing fans provide added protection in both controlled and hostile environments. Typically the exhaust air is diverted out the front vents, or easily changed to vent out the sides or both. 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 electrolyte and are constructed of flame retardant materials.

For more information, see the Battery Technology section. 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.
