About this file
This document outlines requirements for a Direct Current Back-Up System (DC BUS) power supply contract opportunity. The Federal Aviation Administration (FAA) is seeking proposals for a potential ten-year Indefinite Delivery Indefinite Quantity contract to provide life cycle in-service support for DC BUS uninterruptible power supplies. Proposals are due by 2:00pm EST on March 27, 2020. The FAA will provide responses to vendor questions by 5:00pm EST on March 18, 2020. Offerors must comply with submission instructions in Section L and are advised not to expect reimbursement for proposal development costs. The DC BUS equipment must condition and provide uninterruptible electrical power to support critical National Air Space communication and electronic equipment.
