- Description
- This synopsis is being posted to both the Federal Business Opportunities(FBO) page located at http://www.eps.gov and the Navy Electronic Commerce on Line(NECO) site located at http://www.neco.navy.mil. While it is understood that FBO is the single point of entry for posting of synopsis and solicitations to the internet, NECO is the alternative in case FBO is unavailable. Please feel free to use either site to access information posted by NSWC Crane. The Navy is seeking information on a replacement for a power supply to be used in the Cooperative Engagement Capability (CEC) system. The Navy wants to find a potential solution and gather technical and cost information to plan and budget for future requirements. The following are the preliminary requirements of the Power Supply: 1. 12 kilowatts of output power at 270 VDC (no more than 8 kW to be drawn at any time). 2. Modularized construction so that one section of the power supply can fail and the power supply will still source 8 kilowatts of power. 3. Output regulation +/- 5% from zero load to maximum load 4. Ripple maximum +/- 2% 5. Power supply input characteristics - Mil-STD-1399 section 300 type I power 440 VAC, nominal frequency 60 Hz, +/- 5.5% 6. 440 VAC nominal input 3-phase delta with safety ground 7. Input power transient withstanding: a. 1 - 10 msec +/- 1000 Volts peak b. 50 usec +/- 2500 Volts peak 8. Voltage imbalance line to line or line to ground 3% 9. Power factor 0.9 10. Discharge power to less than 30 Volts within 2 seconds of power removal 11. Isolation to main power of 10 Mohms 12. Overload protected 13. Short circuit protected 14. Operate within +/- 20% under no load conditions 15. Operate within output specifications with long term line transient of +/- 20% 16. Component stress levels are not exceeded under input load of +35% 17. Air cooled/conduction cooled to air heat exchanger The following are features that are desired but not required, with weight given to implementation options that include the desired features but not at a large cost, schedule or size impact. We prefer that most of the power monitoring occur in the power supply, but not at a significant cost or schedule increase. Extra circuitry could be added to the system (external to power supply) to address these issues (such as a capacitor bank for the power hold time). Proposals should address what extra circuitry would be needed to meet these criteria external to the power supply, and how much the cost and delivery schedule of the power supply is affected by inclusion of the various features needed to implement these system requirements. 1. Rise time from zero to stable power output is 125 milliseconds or less. 2. Power must be able to switch from a load of 4 killowatts to 8 killowatts while staying within tolerance. 3. A power hold time of at least 50 milliseconds is required after loss of primary power. 4. System must detect when the power supply is operating out of voltage range high. 5. System must detect when the power supply is operating out of voltage range low. 6. System must detect when a phase of the 440 VAC primary power has been lost. 7. System must detect when the power supply is operating out of current range high. 8. System must detect when the power supply is operating out of temperature range high. 9. A green light is needed for each module of the power supply to indicate that the module is functioning properly. 10. A red light is needed for each module of the power supply to indicate that the module is not functioning properly. Respondents should include in submittal the following: proposed approach (including pictures, if available), advantages, disadvantages, the Government?s ability to maintain item, timeline for development and delivery, and Rough Order of Magnitude of cost per unit. Interested companies should provide information along with technical questions regarding this announcement to Mr. Jan Owens, e-mail jan.owens@navy.mil. Responses should be submitted no later than 10 January 2005. Please include the RFI number (i.e., N00164-05-Q-0049) on all correspondence. This notice does not constitute an Invitation for Bids or a Request for Proposal (RFP), and it is not a commitment by the Navy to procure products or services. The Navy is only seeking information for future needs. No RFP solicitation document exists at this time. The Navy does not intend to award a contract on the basis of this Request For Information, and will not reimburse any costs incurred by interested companies resp! onding to this announcement. However, respondents to this Request for Information will not be excluded from consideration for contract participation in any potential follow-on hardware development activity. All information marked as proprietary information will be safeguarded to prevent disclosure to non-Government personnel and entities.
