59 -- SOURCES SOUGHT FOR 500AMP POWER SUPPLY DUE 052297 POC Ken Shedlock, Production Engineer, (908)532-5733 E-MAIL: CECOM POC, shedlock@doim6.monmouth.army.mil. THIS IS A MARKET SURVEY TO DETERMINE THE AVAILABILITY OF A COMMERCIAL-OFF-THE-SHELF (COTS) 500amp POWER SUPPLY; THIS EQUIPMENT (PRODUCT) MUST BE ALREADY COMMERCIALLY AVAILABLE TO CONSUMERS. THIS POWER SUPPLY MUST SATISFY THE FOLLOWING MINIMUM ESSENTIAL REQUIREMENTS: INPUT: 200-245VAC, 3 phase, 50 and 60 Hz operation, 100amps(max) OUTPUT: 28VDC (nominal) at 50 and 60Hz operation, 26-36VDC allowable adjustment range for 60Hz operation, 28-31VDC allowable adjustment range for 50Hz operation; 500amps continuous AC INPUT/DC OUTPUT Wiring Connections: shall be compatible with electrical wiring hook-up configuration of the existing power supply used with the AN/ASM-189(), so that NO modification is required to the van for installation of the power supply. A detailed description of the wiring connections can be provided by the government POC below via FAX, if required/requested by the vendor. OUTPUT CURRENT REGULATION: Static, +/- 0.25%; Dynamic, 5v @ 1/2 load, 8v @ full load. RESPONSE TIME: 100 milliseconds (max) for 63% reduction of transient DC VOLTAGE RANGE: Continuous adjustment available over the entire range. RIPPLE VOLTAGE: 1% RMS (max) SAFETY: The power supply shall meet applicable requirements/standards of the NEC and Underwriters Laboratories Inc 1012. The operator will not be exposed to energy shock as defined IAW UL 1950, para 2.1.10. Equipment grounding shall comply with NFPA 70-93, art. 250 and UL 1950, para 1.6.3 and sect. 2.5. Operator accessible parts shall comply with temperature limits of UL 1950, table 16, part 2. Safety markings and labels shall comply with ANSI Z535.4. Safety labels complying with UL 1950, para 1.7.15 and/or UL 969 are acceptable. TEMPERATURE/ENVIRONMENTAL: Operating, +55 to +95 degrees F; Non-operating, -70 to +155 degrees F (storage). The equipment shall meet vibration req'mts IAW MIL-STD-810E, Method 514.4 Procedure I, Cat. 8 under non-operating conditions; vibration levels shall be IAW applicable profiles, which can be provided by the government POC below via FAX, upon request by the vendor. The equipment shall meet the humidity test of MIL-STD-810C, Method 507.1, Procedure II, under non-operating conditions. Note: This test is performed with the power supply installed inside an equivalent enclosure as the internal cubage of the AN/ASM-189() semi-trailer van (32ft) with the air vents in the open position. OTHER REQUIRED FEATURES: Regulation/Rectification: All solid state design including hermetically sealed components. Peak voltages and currents during operation and switching held within rated values. Circuit isolation: output circuit shall be completely isolated from input; either positive or negative DC bus can be grounded. Sustain overload protection is required. Stability: Negligible temperature influence. Pilot light is required to indicate when unit is energized. Display Meters: Analog/digital voltmeter and ammeter with 2% accuracy (or better) is required. Assessibility: Inside of equipment shall be readily assessible from front for inspection and routine maintenance. Maximum weight: 720 lbs. Maximum dimensions: 24" wide X 25" deep X 39" high. Interchangeability: The power supply shall be interchangeable with existing interface drawings A3059527, A3059530, SM-D-887804, SM-D-887841,SM-D-887842, SM-B-887850, and SM-C-887941, to allow attachment to mounting brackets on AN/ASM-189() without further modification of the van; these drawings can be provided by the government POC below via FAX, upon request by the vendor. Commercial Manual: The vendor shall provide (the government) the equipment's (commercial) Operator/Maintenance/Parts breakdown Manual for review as acceptable usage by soldiers. Also, the vendor shall provide (the government) a specification sheet/company catalog of the above commercially-available equipment. The commercial manual/spec. sheet shall be mailed to: Commander, US Army CECOM, ATTN: AMSEL-LC-CCS-P-GS (K. Shedlock), Fort Monmouth, N.J. 07703-5043. E:Mail address: shedlock@doim6.monmouth.army.mil. CECOM POC is Mr. Ken Shedlock @ (908) 532-5733, or Mr. Stuart Cogan @ (908) 532-0214. The deadline for response to this survey is May 22, 1997.
