61 -- STATIC POWER INVERTER SOL DAAE20-99-T-0195 POC Deb Juhl, AMSTA-AC-PCH-C, (309) 782-3370 E-MAIL: Click here to contact the contract specialist via, juhld@ria.army.mil. DESC: Static Power Inverter. The acquisition will be a five-year Indefinite Delivery Indefinite Quantity (IDIQ) contract with a minimum quantity of 40 inverters and a maximum quantity of 300 inverters over the 5-year period. The proposed contract is 100% small business set-aside (500 employees). FOB is destination. Estimated issue date is 9 Jul 99. Estimated closing date is 23 Jul 99. The item to procure is an electronic device used to convert DC electrical power into AC electrical power. The inverter shall be a stand alone, fixed unit conforming to UL 458, "Power Converters/Inverters and Power Converter/Inverter Systems for Land Vehicles and Marine Crafts." The inverter shall be provided with mounting holes on its base for attachment to a flat deck. Rack-mount and wall-mount configurations are not acceptable for this application. Size: The inverter shall fit within an envelope not more than 12" side-to-side, 8" top-to-bottom, and 15" front-to-back. Input connections: The input connections shall be provided with a cover. Output connections: The inverter shall be provided with a receptacle on its front panel conforming to ANSI/NEMA WD 6, Configuration 5-15R (125 volts, 15 amperes, 2 pole, 3 wire, grounding type). In addition, the inverter shall be provided with terminals to connect wiring for remote outlets. The terminals shall be provided with a cover. The inverter shall provide Ground Fault Circuit Interruption (GFCI) for the output circuit (both built-in receptacle and terminals). Controls: The inverter shall have an "On-Off " switch on the front of the case. Electrical input: The inverter shall operate on DC power provided by a military tactical vehicle electrical system. The inverter shall provide the specified output from input of 22-30 VDC, inclusive. The inverter shall have reverse polarity protection, and shall be immune to spikes and surges from the vehicle electrical system. Spikes: Military vehicle electrical systems may have spikes with an amplitude of up to + 250 VDC, a rise time not exceeding50 nanoseconds, a frequency of oscillation greater than 100 kHz and less than 500 kHz, and an energy content of not less than 15 millijoules. An individual spike lasts less than 50 microseconds, but may take up to one millisecond to decay to the steady-state level. Surges: Surges in the fault-free condition may have an amplitude up to + 40 V and a duration of 50 milliseconds from a source impedance of 20 milliohms. In the single fault condition, surges may have an amplitude of up to + 100 V and a duration of 50 milliseconds from a source impedance of 500 milliohms. Rise and fall times are approximately 1 millisecond. Electrical Output: The inverter shall provide an output of 120 VAC (-10%, +5%), 60 Hz + 0.5%, single-phase. Total harmonic distortion shall be less than or equal to 5%. Power: The inverter shall have an output capacity of at least 1000 watts during continuous operation in ambient air temperatures of 25 degrees F to +110 degrees F, inclusive. The power factor shall be greater than or equal to 0.8. Low voltage: To protect the starting capacity of the vehicle battery, the inverter shall provide automatic shutdown at a steady-state input of 21-22 VDC. To allow for momentary voltage drops, the low-voltage sensing circuit shall incorporate a delay of 1 to 30 seconds. The inverter shall require a manual reset after shutting down for low voltage, and shall draw no current until the reset is activated. The inverter shall also draw no current after being manually switched off. Thermal Overload: The inverter shall provide automatic shutdown when its internal temperature exceeds safe limits. The high temperature limit shall be consistent with the operating temperature range specified in paragraph 3.4. Electrical Overload: The inverter shall be provided with an output overload circuit breaker. Moisture: The inverter circuit boards shall be conformally coated, and the inverter enclosure shall be drip-proof. Electromagnetic Interference: The inverter's electromagnetic emissions shall comply with Federal Communications Commission (FCC) Rules, Part 15, Class A, or equivalent. Intended use: The inverter will be used to power miscellaneous electrical appliances such as incandescent lights, portable computers, NiCad battery chargers, and electric hand tools. It will be mounted inside an Explosive Ordnance Disposal (EOD) Utility Body mounted on an M1097A2 High Mobility Multi-Purpose Wheeled Vehicle (HMMWV). Built-in electrical outlets on the case front panel will be used, but remote outlets may also be installed at other locations within the vehicle. The inverter may be exposed to wind-blown rain when the vehicle doors are open. The inverter will be operated primarily (but not exclusively) while the vehicle is parked, with the engine not running. The inverter must not drain the vehicle batteries to the point that the vehicle engine cannot be restarted. The vehicle may be equipped with a two-way radio, which will be in operation at the same time as the inverter. The inverter must not interfere with radio communications. Sample: Interested parties should be prepared to submit a sample for evaluation within 3 weeks of notification. This solicitation will be issued electronically in accordance with FAR 4.501, 5.102(a)(7) and 14.205-1(c) therefore hardcopies will not be provided. Vendors wishing an electronic copy may download it on or after the issue date by accessing the following address via the internet: http://aais.ria.army.mil/aais/SOLINFO/index.htm. CAUTION: This solicitation will be issued electronically as will any amendments thereto. Because of this, the Government is under no obligation and is in fact unable to maintain a bidders mailing list. It is therefore incumbent upon any interested parties to periodically access the above internet address in order to obtain any amendments which may be issued. Failure to obtain any said amendments and to respond to them prior to the date and time set for bid opening/receipt of proposals may render your bid or proposal nonresponsive and result in the rejection of same.
