- Description
- NA This is a combined synopsis/solicitation for commercial items prepared in accordance with the format in Subpart 12.6, as supplemented with additional information included in this notice. This announcement constitutes the only solicitation; proposals are be ing requested and a written solicitation will not be issued. The combined synopsis/solicitation number is DABJ05-03-T-0139. CLIN 0001 Amplifier, Power, 300-KVA Air cooled Class D, 90% efficient, housed in a 3 bay shielded console, matched to T4000 vibrat or MDL SAI300 (1 EA) with the following: Power Supply, Field for a T4000 vibrator (1 EA), Service, Field Engineer, to provide 2 days of support for system start-up and training (1 EA) in accordance with the following specifications: 1. Scope: This specif ication describes the requirements of a replacement power amplifier to drive an existing government owned shaker Model T4000. A DC field supply shall also be required. 2. Performance criteria: The amplifier shall be one component of a dynamic shaker tes t system consisting of the amp, control system, and an electro-dynamic shaker. The amplifier shall be designed to work in conjunction with existing equipment by providing all the power necessary to drive the existing T4000 shaker, located approximately 50 0 feet from the amplifier, to its full capabilities using existing control equipment. 2.1 Shaker Performance: The Amplifier shall be capable of driving the T4000 shaker to its full potential as detailed in Table 2.4 2.2 Shock Testing: The Amplifier s hall be capable of driving the existing shaker to 150% of the specified maximum velocity during shock testing. This shall be demonstrated in the high field mode. 2.3 Transition: The Amplifier shall be able to make the transition between sine, random an d shock testing, each at their highest level, without the need for amplifier modification or the need to manually change taps on a transformer. 2.4 Effective frequency range: 5 Hz to 2000 Hz; Rated force, sine: 40,000 lbs pk; Rated force, random*: 40,000 lbs rms; Rated velocity: 80 in/s; Rated displacement P-P: 2 in; Rated displacement shock: 2 in; Maximum acceleration: 100 g (* random ratings are wideband 20 - 2000 Hz, 3 sigma acceleration peaks, uniform spectral density, with loads of 1000 lbs or greate r). 3. Minimum Requirements: In addition to the requirements of the previous section, the amplifier shall be a solid state digital switching amplifier utilizing the superior efficiency of IBGT output devices. 3.1 Modular design: Amplifier shall consi st of easily removable power modules, each with a minimum power output of 30 KVA. The amplifier shall be capable of operating at reduced power levels with one or more power modules removed. 3.2 Output: The output of the amplifier shall no be less than 300 KVA. 3.3 Power amplifier shall be housed in a totally EMI shielded console. All joints are to be sealed with EMI gaskets joining plated or copper clad surfaces. Three phase power line filters to prevent conductive emissions must be included, where the 3 phase power enters the amplifier. 3.4 Frequency Response: The frequency response shall be flat (+/- 1 dB) from 10 to 2000 Hz. The amplifier shall be capable of driving the existing shaker across its full effective frequency range (5 to 2000 Hz). 3.5 Harmonic Distortion: At full rated output, the acceleration harmonic distortion at the shaker shall be less than 15% from 5 Hz to 2000 Hz except for 2 peaks less than 25%. 3.6 Noise Level: The noise level of the amplifier shall be at least 60 dB below the full output level. 3.7 Local Control Panel: All indicators, adjustments and switches necessary to monitor and control the amplifier shall be provided at the local operator control panel. This shall include, buttons for startup, sequencing, a mplifier gain adjustment, meters for output voltage and current, switching for sine/random mode selection and indicators of amplifier status. This shall also i nclude the ability to bring up and monitor the shaker field current. 3.7.1 The amplifier shall be designed to operate from a remote control panel if such panel is procured in the future. 3.7.2 In addition to the local control panel, the amplifier shall be configured to allow computer control from a remote location. The computer shall display the complete power amplifier control panel including all status lights, current/voltage meters, startup and operating switches and gain control. All switches and controls shall be mouse activated to startup/shutdown and control the amplifier. In addition, a power-save mode shall be available to allow the power amplifier to be powered off once the vibration test has finished. The computer shall also allow the oper ator to select output voltage and output current limits for each test. The computer shall monitor the actual current and voltage and terminate the test if either limit is exceeded. The remote computer and associated software is not part of the procuremen t, but the amplifier shall include all necessary circuitry and a computer interface port to allow operation as described with the existing VWIN controller. 3.7.3 System Safety Interlocks: The amplifier shall contain the necessary hardware to implement a safety interlock system fully integrated with the shaker and slip table. Interlocks shall be provided to shut the system down if any of the following conditions are present: A. Shaker stroke limit exceeded. B. Shaker maximum operating temperature exce eded. C. Slip table oil pressure failure. D. Shaker temperature limit exceeded. E. Cooling system limits exceeded. F. Shaker field supply failure. G. Amplifier current limit exceeded (user selectable at any level at or below the rated amplifier c urrent) H. Amplifier voltage limit exceeded (user selectable at any level at or below the rated amplifier voltage) I. Amplifier maximum operating temperature. 3.8 Amplifier Input Voltage: The input level require to drive the amplifier to full output sh all not exceed ten volts peak. 3.9 Amplifier Cooling: Amplifier shall be totally air cooled and include all air handling hardware necessary to allow operating at rated force with ambient air temperatures of eighty (80) degrees F. 3.10 Utilities: The amplifier shall operate on the existing utilities listed below: 480 V (+/- 10%), 3 phase, 60 Hz; 120 V (+/- 10%), single phase, 60 Hz. 3.11 Cabling: Existing shaker cables will be used.
