Auxiliary Power Unit   5

** Reposting Synopsis prior to RFP release; sole source to Marvin Land Systems, Inc. (CAGE Code: 064H2) **

The Auxiliary Power Unit (APU) for the M1A2 SEPv3 consists of a belt-driven 28-volt (V) generator, a 2-cylinder air-cooled diesel engine, a control box assembly, and a self-contained fuel supply. Power from vehicle batteries is used to drive the APU generator (in starter mode) through controls on the control box assembly. When in starter mode, the generator turns over the engine through a set of drive V belts. The engine is permitted to warm up, and then the generator is manually switched to load mode to produce electrical charge to vehicle batteries. The 28V Direct Current (DC) generator, driven by the diesel engine, produces an output of 154 to 204 amperes to maintain vehicle battery charge without vehicle engine operation. The APU is a 28V DC nominal power generation subsystem located in the rear left sponson of the M1A2 SEP V3 developed for the purpose of supporting 12 hours continuous silent watch or engine off operation.
