June 22, 1992 -- NEW YORK, NY, MINUTEMAN announced the new MINUTEMAN Power
Master (PM) Series, 600 - 1250VA. The PM Series are advanced, true
sinewave Uninterruptible Power Supplies. These new models are line
interactive, standby UPSs. The PM units are designed to provide superior,
total power protection for computer networks, telephone systems and other
sensitive or critical electronic equipment against all commercial power
problems.

"The MINUTEMAN Power Master gives the user greater efficiency in areas
plagued with brownouts or low voltage," says Les Robertson, vice president
of sales and marketing. "When power is affected, the Power Master uses a
voltage boost to assure the end user of a well regulated, true sinewave
output without using the batteries."

When input voltage is between 92VAC and 103VAC the PM units switch to boost
mode and boost output voltage +12% while continuing to charge the
batteries. If input voltage is 92VAC or over 132VAC, the PM models
automatically switch to inverter mode and run on the batteries maintaining
a well regulated output and automatically switch to AC mode when normal
power returns.

"These unique features make these units as attractive as true on-line UPSs
at the price of a standby. And are even more attractive in international
markets where standby units are less effective due to wide voltage
fluctuations," states Robertson.

The Power Master units can directly interface with every available
operating system and guarantees the user an unattended, orderly shutdown
of the computer system when commercial power is lost for a long period.

Other features include an overload measurement in AC mode that provides the
user with lights and audible alarms when the unit is overloaded, automatic
frequency selection of 50Hz or 60Hz, excellent nonlinear current
capability (crest ratio of 3:1), and automatic unit test each time the
unit is powered on.

"Faulty commercial power can cause all kinds of problems with computers,
telephone and essential office equipment. Now the user can give extra
attention to recurring brownouts and power problems with the MINUTEMAN
Power Master Series," concludes Robertson.

The MINUTEMAN PM series start at $579.00 with excellent distributor
margins. The PM1250 and the PM600 are available for immediate delivery of
domestic and international models through the company's direct response
toll free number (800-238-7272) or through its distributors, dealers and
VARs nationwide. The PM900 (900 VA) will be available for shipping late
summer.

Para Systems is a privately held company founded in 1982. The company is
