Clary Corporation
was founded in 1939 by Hugh L. Clary, an entrepreneurial engineer,
inventor, and executive. The company quickly established itself as a
leading producer of adding machines, cash registers and computer
calculating equipment on an international scale
Clary computers were
used by JPL in 1958 to track a moon probe and Clary UPSs protect
NASA shuttle operations today.
Clary's years of
experience in the computer industry, ranging from rugged printers
and adding machines to minicomputers in the 1950 to 1960's prompted
the company to investigate opportunities in computer power
protection in the early 70's.
Clary concluded it
could produce technically superior devices and set in motion a
research and development program to further this objective. In 1977,
Clary introduced what became the power protection industry's first
complete line of transistorized Uninterruptible Power Systems,
providing compact, quiet operation, fast transient response and low
output impedance - all desirable features for computer and
scientific applications. Hitherto, the industry had relied on
ferroresonant transformer technology (some companies still do) or
silicon controlled rectifiers (SCRs). The former resulted in large,
heavy, noisy equipment, while SCRs, also noisy, were unsuitable in
the low to moderate power range.
In 1984, Clary
introduced the Onguard line of UPS to serve the rapidly growing
mini-computer market in power ranges from 350 VA to 5KVA. This line
represented a significant advance for low-power UPS, incorporating
the latest pulse-width modulated (PWM) power MOSFET technology and
eliminating the output transformers common to competitive UPS of the
day.
In the tradition of
our founder, Clary has continued to be on the cutting edge of
technology with rugged products for mission critical applications.
For the 90's, Clary has developed a new line of Award Winning
Control and Monitoring Software for use with standalone and
inter-networking applications. This Software is both powerful and
easy to install and use. Clary's mission is to provide technically
superior power protection devices which support users of sensitive
computer and electronics equipment in the commercial, scientific and
defense industries.
Uninterruptible
Power Supplies with Power Conditioning
The SP Series Traffic UPS serves three
important functions:
-
Power Conditioning. Lightning spikes, transients and
line noise will burn through and degrade electronic devices over
time. But loads connected to the continuous output of the SP1000™
get 24 hour protection from dirty power as well as regulating
against sags (brownouts) and surges, thus reducing premature
failure and improving equipment performance.
-
Backup power for flashing red signals, up to the
maximum power rating, for any type of signal heads.
-
Continuous Power to your signal controller,
modems, video and other critical devices.
