FOR IMMEDIATE RELEASE

                    AULT INCORPORATED ACQUIRES POWER GENERAL

       STRATEGIC ACQUISITION EXPANDS PRODUCT OFFERINGS, LEVERAGES EXISTING
                  DISTRIBUTION CHANNELS, AND FURTHER ENHANCES
                            ENGINEERING CAPABILITIES

MINNEAPOLIS -- JULY 16, 2002 -- AULT INCORPORATED (NASDAQ: AULT), the leading
North American manufacturer oF external power conversion products, today
announced the acquisition of the operating assets of the Power General division
of Nidec America Corporation located in Canton, Massachusetts. Power General
specializes in custom AC/DC power supplies and DC/DC products. Under the terms
of the asset purchase, Ault paid Nidec $366,000 cash and issued $2,074,000 face
amount of its 7% convertible preferred stock. Ault will maintain Power General's
engineering group in Massachusetts and move Power General's manufacturing
operations to existing Ault facilities in North America and Asia within
approximately six months.

      "We welcome Power General into the Ault family and are pleased to continue
their established record of customer service and engineering excellence," stated
Fred Green, Ault's President and Chief Executive Officer. "This acquisition
further establishes our status as an industry leader, enhancing our product line
and engineering depth, and is a continuation of our efforts to meet the needs of
our customers."

      "The addition of Power General will benefit Ault in a number of ways.
First, the additional engineering capabilities enhance product development.
Second, the acquisition brings greater product breadth to Ault through the
addition of AC/DC power supplies and DC/DC converter products. This broader
offering affords Ault new business opportunities previously unavailable due to a
lack of an internal power supply offering. The expanded product line will be
sold through Ault's well-established network of independent reps and
distributors worldwide."

      "This strategic acquisition changes our short-term profile by adding R&D
expense," commented Donald Henry, Ault's Vice-President and Chief Financial
Officer. "However, our long-term position will be strengthened with enhanced
products, shorter cycle times, and improved profitability."

      Founded in 1979, Power General designs, manufactures and sells
state-of-the art AC/DC switch mode power supplies and DC/DC converters. Its
broad range of standard, modified and custom products focuses primarily on
applications in the wireless and optical telecommunications markets. Power
General sales in fiscal 2002 were $5.3 million.

      Ault is the largest independent manufacturer of external power conversion
products based in North America. The Company is a leading supplier to original
equipment manufacturers of broadband modems, wireless and wire line
telecommunications infrastructure, computer peripherals and medical equipment.
