99 -- SOLICITATION OF MANUFACTURERS OF TRANSIENT VOLTAGE SURGE SUPPRESSION(TVSS) DEVICES SOL N6554000Q0021 DUE 020499 POC Ed Markey (215) 897-7226 Naval Surface Warfare Center, Carderock Division(Code 9343) is soliciting manufacturers of transient voltage surge suppression (TVSS) devices, for a TVSS device to be used on U.S. Naval Platforms. The subject TVSS shall meet the requirements of, references: (1) ASTM-F-1507-94 Standard Specification for Surge Suppressors for Shipboard Use (2) UL 1449 second edition (below 600 Volts) (3) MIL-STD-1399 Section 300 (4) ANSI/IEEE C62.41 (Recommended Practice on Surge Voltage in Low-Voltage AC Power Circuits) (5) ANSI/IEEE C62.45 (Guide on Surge Testing for Equipment Connected Connected Low-Voltage ac Power Circuits) (6) ANSI/IEEE C84.1 (Electrical Power Systems and Equipment-Voltage Ratings) (7) MIL-STD-461D (Requirements for the Control of Electromagnetic Interference Emissions and Susceptibility) (8) MIL-STD-462D (Measurement of Electromagnetic Interference Characteristics) (9) MIL-S-901D (lightweight shock testing) (10) MIL-STD-167/1 (vibration testing) (11) NFPA-70 (National Electric Code, 1996) All TVSS devices must be Commercial Off The Shelf(COTS) products, designed and manufactured using parallel configured, threshold suppression networking and incorporate electrochemical heat sink encapsulation. The TVSS devices must be COTS products, readily availabel and require no engineering redesign to meet the requirements. The TVSS must be maintenance free and come with a 20 year warranty. The TVSS shall: *prevent voltage spikes, as discussed in references (1)-(6), from damaging equipment and reduce downtime due to transient activity *reduce the overall costs of of associated in-line equipment and increase operational efficiency of protected equipment *pose no safety risk to personnel *provide all types of mode protection (line to line, line to neutral, line to ground, neutral to ground) *have a response time of less than one nanosecond *display unit operational status using light emitting diodes and/or indicator lights *be capable of input voltages +/- 25% of design capacity with peak surges to 200,000 total amps for three phase applications and 120,000 total amps for single phase applications *the TVSS shall include sealed solid state circuitry *The TVSS shall include a flanged mounting pattern to allow for mounting to welded studs on a wall or bulkhead *the TVSS shall be delivered inclusive of all shock mounts or other hardware and equipment necessary to ensure that, when installed, will comply with the shock and vibration requirements set forth in MIL-S-901 and MIL-STD-167-1 *the TVSS shall be capable of handling input power freauencies between 50-420HZ *the TVSS shall meet the requirements of NEMA 4(weatherproof enclosure) *the TVSS connection method shall use internal wire clamping box terminals *the TVSS shall be available in three phase and single phase delta wiring configurations as wel as three phase wye configured wiring arrangements *ASTM-F-1507 performance requirements (sect7.1) shall be met, in addition to the following requirements: -minimum life shall be 5000 operations -minimum energy dissipationcapability shall be: 1800 Joules/phase for 3 phase 120VAC applications; 4800 Joules/phase for 3 phase 480Vac applications; 1080 Joules/phase for single phase applications; number of applied voltage impulses and current impulses shall be 2500 each. Surges shall be supplied at 12-second intervals. This announcement is issued to consider all potential sources and does not obligate the Government to award a contract. Descriptive literature, such as specifications, drawing and technical requirements can be forwarded to Ed Markey, Code 9343, Naval Surface Warfare Center, Carderock Division, Philadelphia Naval Business Centera, Philadelphia, PA 19112-5083. NO telephone requests will be accepted. All submissions are due by January 28, 2000. Posted 01/21/00 (W-SN417400). (0021)
