               DEL GLOBAL TECHNOLOGIES DELAYS FILING OF FORM 10-Q

            VALHALLA, NY - June 18, 2003 -- Del Global Technologies Corp. (DGTC)
("Del  Global"  or "the  Company")  today  announced  that it has filed with the
Securities and Exchange  Commission a Notification of Late Filing on Form 12b-25
for its Quarterly  Report on Form 10-Q for its third fiscal quarter ended May 3,
2003.  This filing  provides  for a 5 calendar day  extension  of the  Company's
filing  date for its  Form  10-Q.  The  Company  expects  to be able to file its
Quarterly Report on or before Monday,  June 23, 2003, which would be within this
extension period.

            As a separate  matter and as  previously  announced,  Del Global has
entered into negotiations regarding a comprehensive settlement of the Department
of Defense's investigation into the Company's RFI Corporation subsidiary.  Prior
to preliminary discussions with the U.S. Government in June 2003, Del Global had
no basis to  estimate  the  financial  impact  of this  investigation.  Based on
preliminary  settlement  discussions with the U.S. Government,  discussions with
the Company's  legal  advisors,  consideration  of settlements  reached by other
parties in  investigations  of this nature,  and  consideration  of Del Global's
capital  resources,  management  has now developed an estimate of the low end of
the potential range of the financial impact. Accordingly,  Del Global expects to
report a charge  in its  third  quarter  of  fiscal  2003 of  $2,347,000,  which
represents its estimate of the low end of a range of potential fines and related
legal and  professional  fees in connection  with this  potential  comprehensive
settlement.

            Subsequent  to the  filing of its  10-Q,  the  Company  will hold an
investor conference call on a date to be announced.

            Del Global  Technologies  Corp. is primarily  engaged in the design,
manufacture  and  marketing of  cost-effective  medical  imaging and  diagnostic
systems    consisting    of    stationary    and   portable    x-ray    systems,
radiographic/fluoroscopic   systems,  dental  imaging  systems  and  proprietary
high-voltage  power  conversion   subsystems  for  medical  and  other  critical
industrial  applications.  Industrial applications for which Del Global supplies
power   subsystems    include   airport   explosives    detection,    analytical
instrumentation, semiconductor capital equipment and energy exploration.

settlement of the Department of Defense  investigation on terms that the Company

Government,  and favorable  general  economic  conditions.  Actual results could
