The Dewey Electronics Corporation – Military Diesel Generators and Auxiliary Power Units (APU) for Military Applications

The Dewey Electronics Corporation, a publicly traded small business concern (DEWY-OB), located in Oakland, NJ is a leader in the design and manufacture of compact diesel powered portable generator sets and Auxiliary Power Units (APUs). Our 2kW Military Tactical Generator (MTG) family is the PM-Mobil Electric Power (MEP) type certified standard for US Military use. Dewey APUs provide power for silent watch applications and other custom uses on numerous military vehicles.

Dewey also provides a range of support products for our 2kW MTG including electronic control remote fueling pump kits and tactical quiet flexible soft covers. We also provide various power distribution equipment and power management technologies.

2kW Military Tactical Generator Sets (MTG)

The PM-MEP type certified MEP 95-501A (28VDC) and MEP 95-531A (120V AC) have been the standard man portable generators for the US DoD. Dewey has fielded over 12,000 of these units since 1996. These units operate on diesel 1, 2 or JP-8 fuels.

The MEP 95-501A (NSN 6115-01-435-1567) provides 2kW of 28V DC power. It weighs 148 pounds with 4 hours of fuel.

Man-portable 120V AC power is provided by the MEP 95-531A (NSN 6115-01-435-1565). This unit weights 153 pounds and provides power for four continuous hours before requiring re-fueling.

Full rated operation within the temperature range of -25° F to 120° F the MTGs are the lightest type classified, fully logistically supported generators in the DoD inventory complete with full technical manuals, training and train the trainer support. These highly reliable units meet all Human Factor requirements and have an acoustic noise signature of 79dBA @ 23 ft.

Dewey also provides a 2kW, 28V DC generator that has been specifically designed to charge batteries. The DEWEY–501A-CL features a programmable current limiting voltage regulator that is custom programmed for the battery chemistry to properly charge unique battery types (lead acid, AGM, Lithium Ion, etc.).

2kW MTG Accessories

The Tactical Quiet Soft Cover reduces the 2kW MTG audible noise signature of the open frame by 8 dBA to the tactical quiet level of 72 dBA at 7 meters. The soft cover folds flat, for storage and fits either the MEP-501A or the MEP-531A MTGs.

The Electronic Control Remote Fueling Kit is a self contained system that when installed on the MTG activates when the fuel tank is 1/8 filled and pumps fuel from an auxiliary fuel can or other supply container to refill the fuel tank automatically. The leak free design is equipped with anti-siphon, check valves and auto shut off to prevent spills and fault, run and power indication lights.

The NATO Adapter is a recent addition to the 2kW MTG accessory product line. It attaches to the MEP-501A MTG to provide a receptacle for the NATO plug. This adapter is available in a single or dual configuration.

Military Auxiliary Power Units (APU)

Dewey is ever increasing our standard product line for APUs for military applications. Additionally, we provide customized APUs for unique applications in small and large quantities. Our engineering staff will work with you to provide the optimum solution to your auxiliary power generation needs.

Battery Charger Auxiliary Power Unit (BAPU)

Selected by the USMC, our open frame generator set provides a full 3.5kW military rated 28VDC power supply suitable for vehicle APU use and battery charging under extreme temperatures. The unit features a current limiting programmable voltage regulator, redundant local and remote controls, and a self bleeding fuel system for vehicle or remote fuel tank interconnections. Based on our 2kW military heritage, this unit provides a simple power source that is lightweight yet highly reliable and easy to maintain.

Enclosed Vehicle Power Supply (EVPS)

Recently selected by the USMC, this APU can be mounting in three positions (top, bottom and side) for optimum vehicle installations. The enclosed air cooled generator provides 4.0kW of 28V DC at 70° F and operates from -40° F to 130° F. The APU features a current limiting programmable voltage regulator that can charge various battery chemistries, redundant local and customized remote controls, and a self bleeding fuel system for vehicle or remote fuel tank interconnections. The engine operates on diesel and JP-8 fuels. This enclosed unit has a noise signature of less than 70dBA at 7 meters.

5kVA AC Auxiliary Power Unit

Developed initially to support one of our defense contractors on an USMC program, this open frame APU provides 240V, 60Hz, single phase power that can be used for motor or pump applications. An enhanced air filter system is provided for operation in a sandy and dusty environment. The unit is available to provide 120V, 60Hz, single phase power and also 3-phase outputs in voltages of 120 or 240. Optional equipment includes a cold weather starting kit and remote control panel.

Custom Generator and Auxiliary Power Unit (APU)

Dewey provides custom designed, full military rated generators, and auxiliary power units that range in output from 2.0kW to 10kW and provide 28V DC, 120 VAC and 240VAC power. We offer remote start/stop capabilities, automatic start and stop for battery charging and provide enclosures that reduce the unit’s noise signature to levels as low as 63dBA at 6 meters. These generators and APUs is available in open frame or enclosed configurations directly from The Dewey Electronics Corporation. Dewey can provide full engineering design, manufacturing, test and integration support for all your power generation needs.

Power Distribution and Power Management

Power management and power control/conversion technologies are available from Dewey. We have developed automatic load banks that monitor and automatically switch loads on and off the generators to prevent “wet stacking”. Our power converters (dc to dc) and inverter and control logic have been successfully employed in our other products.

We also offer control and monitoring designs for unique power applications such as pumps, motors, fuel cells/reformers and power electronics for military applications.
