                DEL GLOBAL TECHNOLOGIES ANNOUNCES DEVELOPMENTS IN
      DEPARTMENT OF DEFENSE INVESTIGATION AT ITS RFI CORPORATION SUBSIDIARY

VALHALLA, NY - June 09, 2003 -- Del Global Technologies Corp. (DGTC) ("Del
Global") today announced certain developments in connection with an ongoing
investigation by the United States Department of Defense at its RFI Corporation
("RFI") subsidiary.

The Company reported that subsequent to its Annual Meeting of Shareholders on
May 29, 2003, it was advised by the US Attorney for the Eastern District of New
York that the US Attorney's office is willing to enter into negotiations
regarding a comprehensive settlement of its investigation at RFI. Management
believes that such a potential settlement will include the Company pleading
guilty to certain criminal charges, and agreeing to pay certain fines and
restitution to the US Government in an amount which could be material to the
Company. The Company intends to actively pursue settlement discussions.

The Company believes that any settlement could cause the Department of Defense
("DOD") to seek to limit the ability of the Company to do business with United
States government entities. Such limitations could include seeking a "debarment"
or exclusion from doing business with US Government entities for a period of
time. However, because management believes it has been responsive in addressing
the problems that affected RFI in the past, and RFI is the sole source provider
of certain products, the Company is hopeful that as a result of these
negotiations, its ability to continue providing these products will not be
interrupted. There can be no assurance that a settlement will be reached, or if
reached, that such a settlement would not have a material adverse effect on the
Company's business or operations.

Samuel E. Park, Chief Executive of Del Global said "While the practices
surrounding this investigation pre-date the arrival of the current management
team in 2001, we have been diligently working to resolve this problem. We
believe that we have made substantial progress at RFI. We are guardedly
optimistic we can resolve this investigation with the Government, put this
matter behind us, and RFI can continue to provide this critical technology to
the defense industry."

BACKGROUND

As previously announced, on March 8, 2002 RFI Corporation, a subsidiary of the
Company and part of its Power Conversion Group segment, was served with a
