CECOM Acquisition Center proposes to issue Solicitation DAAB07-98-R-6010 for the design, fabrication and test of one (1) 5 kW high speed (3600 rpm), lightweight alternator with power conversion electronics integrated with a Government Furnished Yanmar engine, and an Option for the delivery of one (1) additional alternator. The alternator and power electronics; herein referred to as a subsystem, shall be capable of providing rated continuous power at 5000 Watts, 0.8pf within a temperature range from -32 C (-25 F) to +52 C (+125 F) at any possible relative humidity within this range. The rating is to be constant at altitudes up to 5000 feet at a temperature of 107 degrees Fahrenheit. The power may be reduced 3.33 per cent for each 1000 ft above 5000 ft. and 1.0 per cent for each 10 degrees Fahrenheit above 107 F. The target weight for the alternator is 25 pounds. If the contractor chooses to employ a R&D power electronics package, the target weight is 25 lbs., with a full heat sink if needed. Thealternator shall be reconnectable for the following outputs 0.8pf, 120 VAC single phase; 120/240 V single phase; and 120/208 V three phase. The alternator subsystem shall have an efficiency of 90% or greater and be compatible with a Yanmar 2TNE68C commercial engine. The Yanmar 2TNE68C engine with a 24 Volt (V) battery charging alternator, 24 V starter, a flywheel and housing, and a pusher fan will be provided as Government Furnished Equipment (GFE) to the contractor. The power electronics package shall provide conditioning and control capabilities at temperatures from -32 C (-25 F) to +52 C (+125 F) at any possible relative humidity within this temperate range, and shall allow for short circuit and overload protection and have long and short surge capability. Release of the Solicitation is anticipated on or about 27 February 1998. Hard copies will not be provided.
