Dewey - Man-Portable Diesel and Heavy-Fuel Generators and Auxiliary Power Units

The Dewey Electronics Corporation, a publicly traded small business concern (DEWY OB), located in Oakland, New Jersey, is a leader in the design and manufacture of diesel-powered portable generator sets and small APUs.

MILITARY TACTICAL GENERATORS

Our 2kW Military Tactical Generator (MTG) family is the PM-Mobil Electric Power (MEP) type-certified standard for US military use. Our quiet, small APUs (2kW to 10kW) 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 MTGs, 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

The PM-MEP type certified MEP95-501A (28VDC) and MEP95-531A (120VAC) have been the standard 2kW set for portable generators for the US Department of Defense (DoD). Dewey has fielded over 11,000 of these units since 1996.

The MEP95-501A (NSN 6115-01-435-1567) provides 2kW of 28VDC power. Weighing 148lbs with four hours of fuel, this portable unit operates on diesel 1, 2 or JP-8 fuels.

Man-portable 120VAC power is provided by the MEP95-531A (NSN 6115-01-435-1565). Fueled with diesel 1, 2 or JP-8, this unit weights 153lb and provides power for four continuous hours before requiring re-fueling.

Designed for full-rated operation within a temperature range of -25°F to 120°F, the MTGs are the lightest type-classified, fully logistically supported generators in the DoD. Their inventory includes 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 at 23ft.

MTG ACCESSORIES

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

The electronic-control remote-fueling kit is a self contained system that, when installed on the MTG, activates when the fuel tank is ⅛ filled. It 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 spill, as well as fault, run and power-indication lights.

BATTERY CHARGER AUXILIARY POWER UNIT (BAPU)

Selected by the United States Marine Corps (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 has redundant local and remote controls, 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, highly reliable and easy to maintain.

APU CUSTOM ENCLOSED GENERATOR

Our custom-designed, fully military-rated 3kW 28VDC power supply has remote start and stop capabilities and is mounted in a noise-dampening enclosure (less than 65dBA at 6m). This APU is available directly from The Dewey Electronics Corporation.

The ruggedized unit is based on our military 2kW unit, with most additional features fully supported by the US DoD logistics system. Dewey can provide full engineering design, manufacturing, test and integration support.

POWER DISTRIBUTION AND POWER MANAGEMENT

We offer power distribution solutions, such as our NATO slave receptacle adapter, which mates with our 2kW MTG or any of our DC APUs and provides 28VDC power output for easy connections to field equipment via a NATO plug.

Power management and power control or 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.
