Product Description
1.1
Theory of Operation
An Uninterruptible Power Supply (UPS) is a system that is installed between the utility
power and the load equipment. The UPS provides steady AC output power during utility
power fluctuations and interruptions.
During normal operation, the UPS utilizes utility AC power and removes high voltage
spikes and transients caused by switching and faults on the main utility. The result of this
process is maximum power conditioning and regulation.
If the AC power supplied to the UPS drops below a specified voltage level, the unit's
batteries automatically begin supplying power instead of receiving it. This insures that the
loads connected to the UPS continue to receive power with no interruption. This power is
provided for a long enough time so that the load can be shut down in an orderly fashion.
This prevents loss of data and possible damage to both hardware and software.
When AC input power becomes available again, operation returns to normal. The UPS
batteries begin to recharge, so they will be ready for the next power interruption.
1.2
Application and use
Toshiba's BLACK GOLD TB on-line Uninterruptible Power Supply (UPS) system provides
continuous computer-grade isolated AC power in a compact, efficient, high performance
unit. The UPS assures safe, reliable operation of critical equipment, ranging from
personal computers to mini-computers to local area networks (LAN). All units feature an
audible alarm that sounds if the battery voltage drops below standard during use. This is
an additional aid to help in retaining the valuable data storage, and all units allow for
computer interfacing.
1.3
Power Backup
During an electrical power failure, the UPS unit's batteries automatically supply DC power
to the inverter that supports the load equipment without interruption. For example, when
used to support a computer, the UPS backup assures additional time to complete your
activity and store data after a power failure occurs.
1.4
Power Conditioning
While utility power is present, the UPS supplies conditioned power to the load while
maintaining its batteries in a charged condition. The UPS protects the connected load
against the normal, everyday problems associated with heavy use of raw utility power,
including power sags, surges, signal interference, and spikes. This protection keeps
power-line problems from reaching your load, where it can cause equipment to operate
erratically, or damage software and hardware.
