Characteristics. The power plants consist of two DOD Model MEP-831A Tactical Quiet Generator
Sets mounted on a modified M116A3 one ton trailer. Each generator set operates at 60Hz and is an air-cooled,
diesel engine driven, single-phase unit, with a load capacity of 3 kW. Refer to TM 9-6115-639-13 for detailed
equipment characteristics about the 3kW generator set. Modifications to the M116A3 trailer chassis used for both
power plants consist of platform/fenders, accessory box, rear leveling-support jack, fire extinguisher/brackets, and
generator set mounting rails. In addition, the AN/MJQ-42 Power Plant trailer contains a stowage rack, used to
carry an antenna mast, mast kit, and mast extension kit, cable reel, mast supports, and antenna mounts. Power
plant output is supplied from either generator set to the system or equipment being powered through a switch box
mounted on the trailer. For operation of a single generator set, the load cables may be connected directly to the
generator set output load terminals. Refer to TM 9-2330-202-14&P for detailed equipment characteristics about
the M116A3 trailer.
