61 -- DC/AC POWER INVERTER, 1KW POC Deb Juhl, Contract Specialist, (309) 782-3370 E-MAIL: Click here to contact the contract specialist via, juhld@ria.army.mil. We are looking for a DC/AC power inverter. We need to know if there are any existing commercial power inverters that meet all of our requirements. If not, can existing inverters meet our requirements with minor modifications? What modifications would be needed? Are there any stated requirements that will reduce competition or increase the price unnecessarily? The inverter will be used to operate a laptop computer, several battery chargers, and miscellaneous electrical appliances. It will be mounted to a deck plate inside a cargo enclosure on a High Mobility Multi-Purpose Wheeled Vehicle (HMMWV) chassis. The inverter will occasionally be exposed to wind-blown rain from an open door two feet away. Requirements: Nominal maximum dimensions are 12" wide by 12" high by 15" deep, including the space required to make input and output connections. Weight shouldn't exceed 20 pounds. The input and output terminals should be on the rear of the case and have a cover. Input power is 24 VDC, nominal. Output power is 110-120 VAC, 60 Hz, single phase, true (pure) sine wave. Rated output capacity is 1 KW nominal for continuous use. Input connections are threaded terminal posts. Output connections: 1 standard duplex outlet (or equivalent) on front panel, plus threaded terminals to connect wiring for remote outlets, including a separate ground. On/off switch should be readily accessible, but protected from accidental operation or shut off. It should have an output overload circuit breaker and an automatic "low battery" shutdown at 21 VDC with a surge delay of at least 2 seconds. It should have indicator lights for power on, low voltage input, overload, high temperature, and low battery shutdown. It should be rated for continuous operation between 25 and +120 degrees F with an automatic "high temperature" shutdown at 120 degrees F. Reduction of rated output to as low as 750 watts for continuous operation at temperatures above 100 degrees Fahrenheit is acceptable. It should have a "drip proof", stand-alone enclosure, suitable for fastening to a flat metal deck. Rack mount configurations are not acceptable. The inverter must be rated for military cross-country vehicle shock and vibration. You may send comments and/or product literature by mail, FAX, or e-mail.
