Since 1996 Dewey Electronics has been manufacturing and supplying the standard 2kW Military Tactical Generator to the US Department of Defense’s PM-Mobile Electric Power (PM-MEP). We have fielded over 17,000 MTGs in this open frame configuration.

Used by the tri-services (U.S. Army, U.S. Navy/U.S.M.C., and U.S. Air Force), it is supported with a full logistic package in the DoD inventory.

Our heavy fuel generators operate on diesel fuels and military fuels (JP-8) and meet all the requirements of Purchase Description PD 6115-0111, dated 1 February 2001.

These compact, portable, highly reliable, lightweight units are available with either 120V AC or 28V DC output and have established themselves as the mainstay of portable power for military applications worldwide. Their open frame configuration allows them to be easily lifted, stacked, or transported by any military vehicle. This open configuration contributes to the ease of maintenance for which these units are noted.

Equipped with a manual recoil starter and the ability to be electrically started from their NATO Slave Connector, these units are used throughout the military where pure military power is a requirement or when portability is a necessity. Now these units are available directly from Dewey Electronics.

The open frame configuration is available as follows:
