    BLACKSBURG, Va., April 1, 2008 /PRNewswire/ -- VPT, Inc., the
 innovative leader in providing power handling products, today introduced
 more than 50 DC-DC converter modules specifically designed and manufactured
 for space applications. Grouped into four product families, these new space
 DC-DC converters deliver up to 120 watts of output power, operate reliably
 through harsh radiation environments, and are available for fast delivery
 at reasonable cost.

     "VPT is the first to provide DC-DC power conversion products with a
 guaranteed radiation tolerance through long-term exposure to low dose
 radiation, the most typical type that affects the success of the mission,"
 explained Michael J. Bosmann, Senior Vice President of Sales and Marketing
 for VPT. "Years ago we were focused on a total dose of 100krad or more, but
 over time the industry has learned that continual low dose radiation is
 much more of a concern and typical of that encountered during the
 application. Our new product line satisfies today's updated reliability
 requirements for space including the new radiation requirements, small size
 and light weight mandates, stringent requirements of 100% reliable
 operation through a wide range of space flight conditions, and fast product
 availability."
 
     Built for Today's Space Requirements
 
     VPT packages its "S" space series of DC-DC converters in miniature,
 hermetic, metal cases for reliable power delivery through the extreme
 temperature, shock, vibration, and radiation environments of space travel.
 Specific features of the new SVSA, SVHF, SVTR and SVFL product families
 include:
 
 

     -- Six to 120 watts of output power in standard single and dual output
        voltages
     -- Characterization and guarantee to 30krads (Si) per VPT's RHA plan
        specified per MIL-PRF-38534, Appendix G, Level P with 2x margin*
     -- Characterization and testing for TID (total ionizing dose) at HDR (high
        dose rate) and LDR (enhanced low dose rate sensitivity -- ELDRS) per
        VPT's RHA plan*
     -- MIL-PRF-38534 Class H element evaluated components standard
     -- Components selected from database of recommended RH devices
     -- Designed and manufactured in a facility certified to MIL-STD-883 and
        MIL-PRF-38534 Class H (military) and K (space) and qualified to
        ISO 9001
     -- Characterization and testing performed at the critical semiconductor
        component piece-part level (radiation lot acceptance test -- RLAT) from
        traceable semiconductor lots
     -- Characterization and testing also performed on the converters produced
        from the same traceable semiconductor lots evaluated during RLAT
     -- No pure tin -- guaranteed
     -- Fault tolerant design with radiation immune magnetic isolation
        technology -- no optoisolators
     -- Wide case temperature operation of -55�C to +125�C with full
        performance over entire temperature range
 
     * VPT's certified radiation program per MIL-PRF-38534, appendix G, is
       currently under review by the Defense Supply Center Columbus (DSCC).
