E-MAIL: Thomas S. Simon, Thomas.Simon@msfc.nasa.gov. NASA/MSFC plans to issue a Request for Quotation (RFQ) for a Power Supply for CDDF. Item No. 1, quantity 1, Unit Each. Specifications: AC input: 480 volts, 3 phase, 60 HZ; DC output: 0-70 volts, 0-3000 Amps; Rating: 100% continuous full load service; Ripple: less than 0.5%; stability: less than 0.5%; control: selectable manual or computer; size: must fit within a space 32"H28"WX57"D, however, designs having widths smaller than 28" would be more desirable. Note: if the DC output requirements cannot be met within the size constraints specified above, then designs which produce the maximum current to a 17 milliohm load will also be considered. This procurement is being conducted under the Simplified Acquisition Procedures (SAP). NASA/MSFC intends to purchase the items from HDR Power Systems pursuant to FAR 13.106-1(b), soliciting from a single source. The desired power supply is identical to other power supplies designed, built and purchased from HDR Power Systems to support an ongoing experiment. This power supply is needed as a spare. Based upon the HDR power supply design, the experiment has been configured such that it can accommodate only this particular power supply both from a physical and control standpoint. Any deviation from the current power supply design would cause immense difficulties with respect to facility modification as well as delaying the completion of the experiment. The Government intends to acquire a commercial item using FAR Part 12. Interested organizations may submit their capabilities and qualifications to perform the effort in writing to the identified point of contact not later than 4:30 p.m. local time on 09/05/2000. Such capabilities/qualifications will be evaluated solely for the purpose of determining whether or not to conduct this procurement on a competitive basis. A determination by the Government not to compete this proposed effort on a full and open competition basis, based upon responses to this notice is solely within the discretion of the government. Oral communications are not acceptable in response to this notice. All responsible sources may submit an offer which shall be considered by the agency.
