                          DEL GLOBAL TECHNOLOGIES CORP.

                      [___________] SHARES OF COMMON STOCK
                  ISSUABLE UPON EXERCISE OF SUBSCRIPTION RIGHTS

      THE SUBSCRIPTION RIGHTS ARE EXERCISABLE UNTIL 5:00 P.M. NEW YORK CITY
                 TIME ON [_______], 2006, SUBJECT TO EXTENSION.

To Our Clients:

         We are sending this letter to you because we hold shares of DEL GLOBAL
TECHNOLOGIES CORP. (the "Company") common stock for you. The Company has
commenced an offering of up to an aggregate of [________] shares of its common
stock, par value $0.10 per share (the "Common Stock"), at a subscription price
of $[____] per share of Common Stock (the "Subscription Price"), pursuant to the
exercise of non-transferable subscription rights ("Subscription Rights"),
distributed to all holders of record of shares of the Common Stock as of
[_________], 2006. The Subscription Rights are described in the Company's
prospectus, dated [________], 2006 (the "Prospectus") and evidenced by a
Subscription Certificate registered in your name or in the name of your nominee.

         The Company has distributed one Subscription Right for each share of
Common Stock outstanding on [__________]. Each Subscription Right entitles the
holder to purchase one share of Common Stock at the Subscription Price (the
"Basic Subscription Right"). Subject to the allocation described below, each
subscription right also grants the holder an over-subscription right to purchase
additional shares of our common stock that are not purchased by other rights
holders pursuant to their basic subscription rights (the "Over-Subscription
Right"). Holders are entitled to exercise their Over-Subscription Right only if
they exercise their Basic Subscription Right in full.

         If you wish to exercise your Over-Subscription Right, you should
indicate the number of additional shares that you would like to purchase in the
space provided on your rights certificate. When you send in your rights
certificate, you must also send the full purchase price for the number of
additional shares that you have requested to purchase (in addition to the
payment due for shares purchased through your basic subscription right). If the
number of shares remaining after the exercise of all Basic Subscription Rights
is not sufficient to satisfy all requests for shares pursuant to all
Over-Subscription Rights, you will be allocated additional shares (subject to
elimination of fractional shares) in the proportion which the number of shares
you purchased through the Basic Subscription Right bears to the total number of
shares that all over-subscribing stockholders purchased through the Basic
Subscription Right. However, if your pro-rata allocation exceeds the number of
shares you requested on your rights certificate, then you will receive only the
number of shares that you requested, and the remaining shares from your pro-rata
allocation will be divided among other rights holders exercising their
Over-Subscription Right. See "The Rights Offering--The Subscription
Rights--Over-Subscription Rights" in the Prospectus.




         We are (or our nominee is) the holder of record of Common Stock held by
us for your account. We can exercise your Subscription Rights only if you
instruct us to do so.

         We request instructions as to whether you wish to have us exercise the
Subscription Rights relating to the Common Stock we hold on your behalf, upon
the terms and conditions set forth in the Prospectus.

         We have enclosed your copy of the following documents:

         1.   Letter to Shareholders from the Company;

         2.   Prospectus;

         3.   Instructions for Use of Del Global Subscription Certificate; and

         3.   Beneficial Owner Election Form.

         The Subscription Rights will expire if not exercised by 5:00 p.m., New
York City time, on [___________], 2006, subject to extension (the "Expiration
Date"). Any Subscription Rights not exercised prior to the Expiration Date will
expire and will have no value. Any subscription for shares of Common Stock in
the rights offering made hereby is irrevocable.

         The materials enclosed are being forwarded to you as the beneficial
owner of Common Stock carried by us in your account but not registered in your
name. Exercises of Subscription Rights may be made only by us as the record
owner and pursuant to your instructions. Accordingly, we request instructions as
to whether you wish us to elect to subscribe for any shares of Common Stock to
which you are entitled pursuant to the terms and subject to the conditions set
forth in the Prospectus. However, we urge you to read the Prospectus and other
enclosed materials carefully before instructing us to exercise your Subscription
Rights.

         Your instructions to us should be forwarded as promptly as possible in
order to permit us to exercise Subscription Rights on your behalf in accordance
with the provisions of the rights offering.

         If you wish to have us, on your behalf, exercise the Subscription
Rights for any shares of Common Stock to which you are entitled, please so
instruct us by completing, executing and returning to us the "Beneficial Owner
Election Form" included herewith.
