RECOVERY-PROJECT DPW 2K007-8J The US Army Corps of Engineers, Alaska District intends to specify an Uninterruptible Power System (UPS) for use in an upcoming project. This market research is to identify if there are sources available to meet the exact specifications as outlined in this sources sought notice, while meeting the restrictions contained under FAR 52.225-9, Buy American Act-Construction Materials, and if there are other products other than the brand name. THIS IS NOT A REQUEST TO PURCHASE THE SYSTEM, but to determine if there are alternative sources available in the commercial off-the-shelf marketplace that meets the salient features of the brand name item. The item description is APC Symmetra PX125/250kW, 480V System only. •A. This specification describes the operation and functionality of a continuous duty, three-phase, solid-state, on-line double conversion static Uninterruptible Power System (UPS) hereafter referred to as the UPS. The UPS shall utilize a rack-mounted N+1 redundant, scalable array architecture. The system power train shall be comprised of 25kVA/25kW power modules and be capable of being configured for N+X redundant operation at the rated system load. In systems operating at a load where the system is N+1 or greater, the UPS shall facilitate the replacement of power modules while the system remains in normal operation, without the requirement to transfer to bypass (hot swappable). •B. Each 25kVA/25kW power module contains a fully rated, power factor corrected input rectifier / boost converter hereafter referred to as the PFC input stage, a fully rated output inverter, and battery charging, circuit. The system shall also be comprised of a hot swappable continuous duty bypass static switch module, redundant control modules, redundant logic power supplies, and touch screen user interface/display. Hot swappable / user replaceable battery modules shall be available as an option. All of the above system components are housed in a standard APC Netshelter SX Racks and SX half rack with the following dimensions, 600mm (W) x 1070mm(D) x 2000mm(H), 750mm (W) x 1070mm(D) x 2000mm(H) and 300mm (W) x 1070mm(D) x 2000mm(H). C. The new unit must be compatible w/the existing APC Symmetra 80kW units, i.e. the new unit has to be able to communicate status as well as function in concert with the existing APC units. This will ensure that a failure of any of the units gets the dormant unit online automatically.
