- Description
- This notice is a combined synopsis/solicitation for commercial items prepared in accordance with the format in FAR Subpart 12.6, as supplemented with additional information included in this notice. This announcement constitutes the only solicitation; quotes are being requested and a written solicitation will not be issued. This procurement is being issued as a Request for Offer (RFO) for Item 1: one (1) high power DC Power Supply System, Item 2: two (2) sets of documentation, and Item 3: Standard Warranty for Item 1. The Contractor shall furnish the above items in accordance with the following specifications. Electrical Requirements: 1. Output Rating: Shall be 0-150 VDC, 0-6000 amps, 100% rated load current continuous at 40 degrees C ambient temperature. Output shall be able to accommodate the test values specified in Table 1. Maximum power output is not expected to exceed 150 kW as indicated by Table 1. The use of multiple units arranged in parallel to achieve a higher current output shall not be considered. Typical research hardware load is a metal resistive tube that is heated to investigate various fuel thermal stabilities and physics. The following table lists expected voltage and current test settings, based on various materials and fuels. Multiple voltage taps to achieve the test matrix may be required. If multiple taps are used, a means of selecting the desired tap either manually or remotely shall be provided without the user having to reconfigure wiring or remove access panels. Table 1 Output DC Voltage/ Output DC Current 2.9 volts/ 1881 amperes 3.2 volts/ 1969 amperes 6.4 volts/ 2512 amperes 7.2 volts/ 2609 amperes 8 volts/ 177 amperes 27.3 volts/ 201 amperes 30.5 volts/ 211 amperes 42.4 volts/ 389 amperes 49.6 volts/ 389 amperes 25 volts(low resistivity test)/ 6000 amperes 100 volts(high resistivity test)/1500 amperes 2. Output Regulation: The combined effect of +/- 10% line variations and 100% load variations shall be less than +/-1% in the voltage and +/-1% in the current regulating mode. The unit shall transfer smoothly and automatically between voltage and current regulation. 3. Transient Response: The unit shall be equipped with a soft-start and ramping capability. 4. Ripple: Output ripple Root Means Square (RMS) shall be less than 5% of rated output in the voltage regulated mode and 5% in the current regulated mode for any output voltage or current. 5. Remote Programmability: The unit shall have the capability to be remotely programmed, in the voltage and current regulating modes, for the following functions: on/off, output voltage setting, and output current setting, with programmable ramp rate capabilities. Remote programming functions shall be electrically isolated and shall be by externally supplied analog voltages. Remote voltage sensing capability is also required. The power supply shall have the ability to be remotely shutdown and reset if an over-voltage or over-current condition occurs. The ability to remotely switch polarity of the power supply shall be provided. This function shall be used only during zero current conditions; hot switching of the load polarity shall not be done. The front panel controls for manual control shall include stop/start, voltage and current set-point adjustments, and contain indicators for power on and fault conditions. 6. Input Voltage: The input voltage shall be 480 VAC +/-10%, three-phase 60 Hz. A suitable ground connection shall also be provided on the unit. 7. Supply and Load Protection: The unit shall incorporate circuit breakers in the input AC line to protect the power circuits in case of failure, and include protection for loss of phase or phase rotation reversal. The input AC breaker shall be capable of being remotely tripped via the user. An adjustable over-voltage and over-current set-point ability shall be incorporated to protect the load in case of supply or programming failure. Thermal overload protective devices shall be built into the design. 8. Operation: The unit shall be operated, tested, and functionally checked prior to shipment to NASA. Physical Requirements: 9. Display: The output voltage and output current shall be displayed on the unit via analog or digital meters. The ability to remotely monitor the output voltage and current levels via isolated analog outputs voltages is also required. 10. Cooling: The unit shall be designed with the appropriate cooling methods for a device of this rating and operate without de-rating over the range of 10-40 degrees C (50-104 degrees F) ambient. Water cooling shall be the preferred method over air cooling since the planned location is not designed with room air conditioning. Unit shall be capable of accepting city water inlet temperatures as low as 50 degrees F without adverse effects. 11. Transportability: The unit(s) shall be able to be moved easily by forklift without incurring any damage to the unit or causing safety hazards. If the power supply must be shipped disassembled, detailed assembly instructions shall be provided to NASA. Documentation: 12. Two (2) operation and maintenance manuals shall be supplied by the vendor. A description of the manufacturer's warranty and any other terms relevant to the system offered shall be included. The provisions and clauses in the RFQ are those in effect through FAC 01-07. This procurement is a total small business set-aside. See Note 1. The NAICS Code and the small business size standard for this procurement are 335311 and 500 employees, respectively. The quoter shall state in their quotation their size status for this procurement. All qualified responsible business sources may submit a quotation which shall be considered by the agency. Delivery to NASA Glenn Research Center is desired within twelve (12) weeks ARO. Delivery shall be FOB Destination. The DPAS rating for this procurement is DO-C9. Offers for the items(s) described above are due August 27, 2002 by 4:30 p.m. EDST, and may be mailed or faxed to Gloria J. Rhyner, Mail Stop 500-306, 21000 Brookpark Road, Cleveland, OH 44135, FAX (216) 433-5489.
