ITEM 5.  OTHER EVENTS

         OnLine Power Supply,  Inc.  announced December 11, 2001, the release of
its  revolutionary  new isolated 48-volt AC to DC power supply unit. This 48 Vdc
power supply has been in development for three years.

         Prototypes  for  evaluation  of the  1,000-watt  power supply are being
shipped to original equipment manufacturers (OEMs), who have expressed continued
interest in the new product during the design and testing phase.

         The 48 Vdc power supply  incorporates the company's  sophisticated  new
Distributed  Power  Magnetics(TM)   (DPM)  technology,   the  first  significant
breakthrough  in power  supply  development  in 23 years.  This  patented/patent
pending  technology  results in AC to DC power  supplies that are  significantly
smaller,  lighter,  cooler and more efficient than other AC to DC power supplies
available  in the market.  DPM also  provides  superior  MTBF (mean time between
failure)  statistics.  The company's  marketing  efforts for the 48 Vdc units is
geared toward the top 50 electronics and  telecommunications  companies in North
America,  and work is under way with OEMs to secure long-term design-in business
for the 48 Vdc power supply.  No contracts are in hand to sell the 48 Vdc units,
and presently there are no design-in contracts with OEMs.

         The new unit provides  packaged  power  efficiency of about 91 percent,
meaning only 9 percent of the energy  created is lost through heat  dissipation.
This is a dramatic  improvement over the current  industry  standard of 75 to 85
percent efficiency.

         The 48 Vdc power  supply is .99 power factor  corrected  and provides a
packaged power density of 15 watts per cubic inch,  giving design engineers more
power in a box one-third  the size of  competitors'  models.  It also provides a
significant weight reduction,  compared to competitors' products. The 1,000-watt
48 Vdc power supply weighs less than 3 pounds, while competitors' 500-watt units
weigh between 4 and 6 pounds.

         The company's 48 Vdc power supply represents the opportunity for design
engineers to add more power to the system in less space,  while  generating less
added heat in proportion to the increase in power.  In turn,  designers have the
opportunity to add more user-friendly  features and components without exceeding
the thermal budget (the system's cumulative operating temperature),  for a final
system product which is a smaller, faster, cooler, and more powerful server.

         Other  applications  of  the  new  power  supply  may  be  made  in the
telecommunications  and data  storage  industries,  as well as in ATMs and other
high-tech products.

         The company has been testing the 48 Vdc power supply in preparation for
UL certification.  Pre-production  work at the manufacturing plant will begin in
the coming weeks.

         OnLine Power Supply holds a U.S. patent for the process of producing AC
to DC power  supplies  that  provide  efficiencies  of up to 97  percent,  power
densities of more than 16 watts per cubic inch, operating  temperature ranges of
- -40 to +85 Celsius,  all with no thermal  deration.  This  technology  is called
Distributed Power Magnetics(TM) (DPM) and is the first significant  breakthrough
in power supply in over 23 years.  The  sophisticated  DPM products also operate
without  cooling  fans or  extraneous  heat  sinks  and  boast  impressive  MTBF
statistics,  all in the  lightest  and smallest  footprint  available  for their
particular configurations. Benefited industries include telecommunications, data
communications, networking and industrial.
