TSi
Power Supplies Federal Aviation Administration with TSi UPS
Since 1991, TSi Power has
been providing the Federal Aviation Administration (FAA) with UPS
systems designed to provide 6 to 8 hours of battery back-up time in
hostile environments. The TSi UPS systems back-up signal transmitters
that send critical flight information to all airplanes approaching any
airport for landing. The transmitters and UPS systems are housed in un-manned
and non-air conditioned equipment huts that are subject to extreme
temperature swings between winter and summer. Several hundred systems
were installed nationwide and have been operational since 1991 with
minimal field problems. The FAA was so impressed with their
performance that they have continued to install our UPS systems at
hundreds of sites. So if you have a system that is exposed to harsh
conditions, then a rugged TSi UPS is your solution!
TSi
Power Backs Up the Presidential Telecommunications System with UPS and
ARm-1000 Automatic Transfer Switches
There is no more mission
critical communications system than the Presidential
telecommunications system run by the State Department. It is
responsible for routing and tracking all telecommunications between
the White House and the world. This system is backed up with both a
TSi Power UPS system and a large generator UPS system to provide
back-up power redundancy. In case of a problem with the primary AC
source, TSi Power’s ARM-1000 Automatic Redundancy Module
automatically detects the failed AC line and seamlessly transfers to
another AC source without interruption. In the most unlikely event
that even the back-up AC source is also defective, a second ARM-1000
can automatically select the second back-up AC source. There is no
limit to the levels of redundancy that can be applied to these mission
critical systems. By using multiple ARM-1000 units, as many layers of
independent power back-up can be achieved as there are power sources
available. Independent power sources include battery back-up,
alternate utility circuit (from a different power grid), and emergency
AC generator sets to name a few. If your system is truly mission
critical, then TSi Power has the solution!
The
United States Army Relies on TSi Power AC Line Conditioners for
Demanding International Applications in the Field
Having access to accurate and timely information is
the key to success in any field in the world, and the Armed Forces are
no exception. The U.S. Army was dispatched to Bosnia to serve as part
of a peacekeeping force to help end the brutal conflict engulfing that
region. In 1997, Army Intelligence, which was responsible for
gathering, disseminating and forwarding vast quantities of information
to the peacekeeping forces, ran into some problems. During much of
their operation, utility power was unavailable. They also found that
their UPS technology was not capable of handling the large numbers of
spikes, surges, sags and brownouts that were present on the AC line.
As a result, the back-up UPS systems they relied on to maintain their
computer networks were actually burning out. When all their UPS were
gone, they hooked their computers directly into the field generators
set up in their camps. This caused catastrophic computer failure.
Since an army with no information is no army at all, the U.S. Army
turned to TSi Power to create a quick solution. Within a few weeks,
the U.S. Army Intelligence was up and running without fear of burning
up their UPS systems or their computers after installation of rugged,
generator compatible line conditioners from TSi Power.
Major
Drug Store Chain Powers Through an Earthquake with TSi UPS
In 1989, a significant earthquake hit the San
Francisco area causing millions of dollars in damage and interrupting
the basic utilities for the area residents. Panic gripped many of the
residents who immediately went to buy emergency food supplies,
candles, flashlights, batteries, etc. TSi Power’s UPS systems were
backing up three drug stores in San Francisco at the time of the
earthquake. These drug stores were open a full eight hour business day
entirely on TSi back-up power. The drugs stores’ point-of-sale (POS)
computers equipped with these UPS systems continued to operate and
record unprecedented sales because all the other drug stores were shut
down. This incident convinced the drug store’s corporate executives
that extended battery UPS systems were a necessity for uninterrupted
operation of retail stores during emergency situations. TSi has the
solution for all retail and service industry power protection and
back-up power problems!
Medical
Equipment Manufacturer Utilizes TSi Power UPS and Battery Extension
Units for Patient Respirators
A leading manufacturer of medical technologies for
critical care patients. Since 1990, a leading intensive patient care
respirator manufacturer has been using a customized
version of TSi Power’s UPS and Battery Extension Units to provide
continuous AC power to respirators of critically ill patients. The
respirator and UPS system are attached to the patient’s portable bed
and moved around inside the hospital (e.g. from the operating room to
the recovery room) by simply unplugging the UPS from the AC socket. In
order to meet the stringent European medical equipment safety
standards, TSi Power’s engineers worked closely with
manufacturer’s engineers to implement the necessary modifications to
the existing models.
Applied
Energy Concepts, a Partner of TSi Power, Solves Telecommunication
Problems in Emerging Markets
In January 1998, TSi Power joined with Applied Energy Concepts to
increase its range of power quality products and applications on the
market today. Applied Energy Concepts develops solutions that control
electrical surges and regulate voltage for mission-critical electronic
systems. These international applications have included protection for
switchmode rectifiers, power supplies and uninterruptible power
systems.
A major cellular infrastructure supplier’s
experience has revealed that conventional surge protection devices
have little impact on equipment failures and often fail themselves as
a result of inadequate power generation and distribution
infrastructures. In thousands of installations worldwide, AEC
equipment has proven to consistently reduce high failure rates of
telecom rectifiers, UPS, and other equipment connected to the power
line. Critical loads such as base transceiver stations (BTS) and nodes
for wireless-in-the-local-loop applications as well as other outdoor
enclosure installations often require this additional protection.
In 1996, TSi Power was asked to assist a large farming
product manufacturer in the middle of Georgia. Nearly one hundred
cabinets that control the automated manufacturing equipment had to be
manually reset after each power outage (even though they were
protected by a well-known, national brand UPS). Each manual reset
operation meant a down-time of over one hours for the entire plant and
financial losses were piling up quickly, especially during summer
months when a number of power outages can occur in a week.
After careful analysis of the problem, TSi engineers concluded that
the problem was caused by a lack of voltage regulation, lack of
isolation and power conditioning, and long transfer time (up to 8
milliseconds) of the existing standby UPS units. They recommended the
Premium Series UPS-16000 with built in CVT (constant voltage
transformer with 100% input/output isolation) and zero transfer time.
The result was spectacular. The controller cabinet protected by the
TSi Power Premium Series no longer required a manual reset after a
power outage while the identical control cabinet powered by the
original standby UPS needed a manual reset after each power outage.
By the middle of 1997, the manufacturing plant
management decided to replace all of their existing UPS units with TSi
Power Premium Series UPS-16000 units. TSi Power is also helping in the
disposal of the old standby UPS units that are being replaced since
the lead-acid batteries inside the old UPS units must be recycled
properly.
