Replace and Installation of New Uninterruptible Power Supply (UPS) for 51 FW/CS at Osan AB

The 51st Fighter Wing Communications Squadron at Osan Air Base in South Korea is seeking market research through a sources-sought synopsis to identify qualified vendors capable of replacing the existing EATON 9395 uninterruptible power supply (UPS) with a new 225KVA system operating at 480V, 3-phase, 3-wire, with efficiency up to 97% and UL certification. The replacement will be installed in Building 946, also known as the Pacific Air Simulation Center, and requires the removal and disposal of the current unit, potential modification or bypassing of two transformers, and integration with existing power infrastructure while maintaining compatibility with 120 existing C&D Technologies 12V 109AH VRLA batteries. The new system must provide seamless power continuity for critical IT and security systems during the 3 to 10 seconds it takes for the facility’s generator to come online. Performance must occur within standard work hours of 0800 to 1600 Korea Standard Time, Monday through Friday, excluding holidays, and all work must be coordinated in English with the on-site facility manager, Mr. David Signorini, who serves as the contracting officer representative. Contractors must have unescorted access to Osan Air Base but will be required to be escorted on the second and third floors of Building 946. All deliverables include full installation, operation and maintenance manuals, detailed wiring diagrams, service documentation, and training for facility personnel on operation of the bypass switchboard and emergency shutdown procedures. The contractor is responsible for testing and validating the system’s performance under load conditions and must provide a one-year warranty covering all materials and workmanship from the date of acceptance. This solicitation, numbered F3J0CP6126A001 and posted on June 10, 2026, with a response deadline of June 19, 2026, is a non-binding market research effort under NAICS code 335999, with no formal pricing or award anticipated at this stage. The Department of Defense, through the 0906 Aq Co Contracting Battalion, is the procuring agency, and no U.S. security clearance is required for contractor personnel.
