Exhibit 99.1


                                                RELEASE DATE: JANUARY 22, 2007

FOR IMMEDIATE RELEASE

                          DEL GLOBAL TECHNOLOGIES CORP.
                         ADOPTS SHAREHOLDER RIGHTS PLAN

      FRANKLIN  PARK,  IL,  January  22, 2007 -- DEL GLOBAL  TECHNOLOGIES  CORP.
(DGTC)  ("Del  Global"  or "the  Company")  today  announced  that its  Board of
Directors  has adopted a shareholder  rights plan that is primarily  designed to
protect  the  Company's  net  operating  loss  carryforwards  ("NOLs")  for  tax
purposes.  NOLs are past losses that a corporation can use to reduce its current
or  future  taxable  income.  The  Company's  ability  to use the NOLs  could be
substantially  reduced if the  Company  experiences  an  "ownership  change," as
defined under Section 382 of the Internal Revenue Code (the "Code").

      "After  careful  consideration,  the  Company's  Board  of  Directors  has
determined  that  it is in the  best  interests  of the  Company  and all of its
stockholders  to adopt the rights  plan at this  time,"  said  James A.  Risher,
President  and Chief  Executive  Officer of the  Company.  "NOLs have  become an
increasingly  valuable  asset to the Company and its  stockholders,  and we hope
that the rights plan will help safeguard the  availability  of this asset to the
Company. However, while the rights plan has been designed to protect the NOLs to
the extent possible, it cannot ensure the protection of the NOLs."

      The rights plan is  designed to deter any person or group from  becoming a
4.99 percent or greater  beneficial  owner of the Company's  Common  Stock.  The
rights plan also discourages, with certain exceptions,  existing 4.99 percent or
greater  beneficial owners from acquiring any additional shares of Common Stock.
Section 382 generally  restricts the use of NOLs after an "ownership  change" to
an annual  amount equal to the value of the company  (generally  measured by the
value of its outstanding stock) multiplied by the long-term  tax-exempt rate. An
"ownership  change" is  generally a more than 50  percentage  point  increase in
stock ownership,  during a moving 3-year testing period,  by "5%  shareholders".
The  percentage  of stock  owned is  calculated  by dividing a person or group's
share ownership over the total stock  outstanding.  The terms of the rights plan
permit the Board of Directors, in its discretion, to determine that a particular
person's  beneficial  ownership of 4.99% or more of the  Company's  Common Stock
will not jeopardize or endanger the Company's  NOLs, and to exempt such person's
ownership of shares from triggering the rights plan.

      As part of the  adoption  of the  rights  plan,  the  Company's  Board  of
Directors  declared a dividend of one right for each share of Common  Stock held
of record as of the close of business on February 2, 2007 payable on February 2,
2007.  The  rights  may cause  substantial  dilution  to a person or group  that
attempts to acquire  4.99  percent or greater of the  Company's  Common Stock on
terms not  approved by the Board of  Directors.  Acquisitions  of the  Company's
Common Stock that would otherwise trigger the rights under the terms of the plan
are  permitted  where the entire Board of  Directors  has  determined,  prior to
consummation,  that the  transaction is fair to and in the best interests of the
Company's  stockholders.  In addition, the Board of Directors may redeem all but
not less than all of the rights,  in its  discretion,  at a redemption  price of
$0.01 per right at any time until the close of  business on the later of (i) the
"distribution  date"  under  the  terms  of the  rights  plan  and  (ii)  "share
acquisition date" under the terms of the rights plan.
