59 -- AC/DC POWER ADAPTER FOR TACTICAL UHF SATCOM TERMINAL SOL F1962800R0039 DUE 041000 POC William Donaldson, Contract Specialist, 781-271-6091 WEB: ESC Business Opportunities Web Page, http://www.herbb.hanscom.af.mil. E-MAIL: Click Here to E-mail the POC, bill.donaldson@hanscom.af.mil. Power Adapters and other accessories (AC/DC input cabling and operations and maintenance manual), Maintenance (optional). The = MILSATCOM Terminals Program Office is seeking commercial off-the-shelf (COTS)/non-developmental item (NDI) AC/DC Power Adapters (herein = referred to as the adapter) for use with Ultra-High Frequency (UHF) satellite communications (SATCOM) terminals in Air Force fixed-site and transportable ground tactical operations. The adapter shall be electrically and physically compatible with Receiver/Transmitter (R/T) types, specifically the AN/PSC-5A and the Multi-Band, Multi-Mode Radio (MBMMR) manufactured by Raytheon Systems Corporation-Fort Wayne, IN. = When equipped with an internal rechargeable battery, the adapter shall = provide uninterruptible power to the R/T in situations where input AC or DC = power is interrupted. As an objective, the internal battery type shall be one that is available within the military supply chain. DC output characteristics of the adapter include regulated 24 VDC nominal output (objectively +5,-0 VDC) at sufficient current to operate the specified R/Ts at rated transmit power, and as an objective at such = output current without the need for an internal battery. As a minimum, with normal input power, it shall be possible to support R/T operation at maximum transmit power on a continuous basis for at least 1 hour = without completely discharging the internal battery. Input power shall be = either AC or DC, prioritized on AC if both are present. AC input = characteristics shall range from 95 to 130 VAC, 47 to 440 Hz or 95 to 240 VAC, 47 to 63 Hz. DC input characteristics shall range from 11 to 33 VDC. The = adapter shall completely recharge the internal battery in 4 hours or less. An auxiliary output of 24 VDC nominal at up to 1 Ampere shall be provided through a separate connector. As = an objective, this connector will interface directly or through a short adapter cable with a type MS3116F8-2P cable plug (pin A +24 VDC, pin B Ground) as used with ancillaryequipment. Input and output circuits = shall include EMI filtering, with objective EMI performance levels compatible with appropriate line conducted, line emission and radiated = requirements of MIL-STD-461E. Protection for over-temperature, and output = over-voltage and short-circuit conditions are desired features. The AC input line shall be protected by circuit breakers or fuse. DC input voltage surge suppression capability shall be at least 100 V, and objectively = compatible with MIL-STD-1275. Physical dimensions shall be compatible with the specified R/T(s) battery side interface (nominally 9.2 x 2.9 inches) by 8.0 inches maximum depth. Weight (less internal battery) shall be less than 4 pounds. = Environmental capabilities shall include an operating temperature range of -30=B0 C = to +55=B0 C, with -30=B0 C to +70=B0 C as an objective, and a = non-operating range of -40=B0 C to +70=B0 C. The adapter shall physically interface to the specified R/Ts with two over-center latches. When mated with an R/T =with sealing gasket, the adapter shall not leak under 3 feet immersion in seawater. Other environmental characteristics shall include operation = in up to 95% relative humidity, including condensation, operating altitude = of 15,000 feet and non-operating altitude of 40,000 feet, and sand and = dust environments. Cooling shall be by free convection only. Items to be supplied with the adapter include internal battery, AC/DC input cabling (AC input termination in grounded North American style line plug, and = DC input termination as insulated plug or clip), and an operation and maintenance manual. When calling, be prepared to state name, address, and solicitation number. Respondents to this synopsis/solicitation should identify whether they = are a large or small business and provide their company's name, address, telephone number, and a Point of Contact (POC). Any proprietary information submitted should be identified as such. The Government = will not reimburse respondents for any cost associated with submission of = the information being requested or reimburse expenses incurred to = interested parties for responses to this synopsis.
