PD Systems Delivers New PU500 Power Unit

Job FairALEXANDRIA, VA, April 26, 2011 – PD Systems , a privately held Service-Disabled Veteran-Owned Small Business, announced today that they have delivered two of their new PU500 power units to the 17th Air Force, located at Ramstein Air Base, Germany, which serves as the air and space component to U.S. Africa Command (AFRICOM). The units, comprised of 500KW 480VAC/60Hz generators, were designed using a Volvo TAD1642GE engine to drive a Marathon 572RSL series alternator which is controlled by an electronic engine controller and automatic voltage regulator for stand-alone and isochronous parallel operations. The power unit is a prime power configured unit installed on a rugged tri-axle trailer with a 500 gallon fuel tank integrated into the trailer base. The PU500 works with the new Low Voltage Secondary Distribution Centers (SDCL), a 480VAC input version of the standard SDC used by the military. A single PU500 can supply power up to four (4) SDCLs daisy-chained together with a second PU500 connected to the system as an alternate power source, providing redundancy to the distribution system. PD Systems also provided equipment familiarization and operation training to include operations and training manuals.
