1600XP Series Installation and Operation Manual
9. Product Description
An uninterruptible power system (UPS) is a system that is installed between the commercial power and the
load equipment. The UPS provides steady AC output power during commercial power short-term blackouts
or brownouts. This power is provided for a sufcient amount of 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.
During normal operation, the UPS uses commercial AC power. It absorbs all of the high voltage spikes and
transients caused by switching and faults, and all of the common-mode and normal mode noise which is
associated with commercial AC power. The UPS converts it all to clean DC power. From this power, the
UPS charges its batteries and generates its own extremely high quality AC waveform output. The result of
this process is maximum power conditioning and regulation.
If the AC power supplied to the UPS drops below a specied 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. When AC input power becomes available again, operation returns to
normal. The unit’s batteries begin to recharge so they will be ready for the next power interruption.
9.1 Application and Use
Toshiba 1600XP Series of On-Line UPS provides continuous computer-grade AC power in a compact, high
performance, and energy efcient unit. The UPS unit ensures safe and reliable operation of critical ofce
equipment. All units feature an audible alarm which sounds if the battery voltage drops below a specied
minimum during use. This is an additional aid to help protect valuable ofce data banks. All units allow for
computer interfacing.

All models are RoHS compliant with the batteries being exempt from the directive.
*NOTE: Derate to 18.7 kVA (15.9 kW) for 50 Hz operation.
9.3 Power Backup
When an electrical power failure occurs, the UPS’s internal batteries automatically supply back-up power
to the load without interruption. For example, when used to support a computer, the UPS back-up assures
enough additional time to complete the activity and store the data. This allows an orderly shutdown after a
power failure has occurred.
9.4 Power Conditioning
When commercial power is present, the UPS supplies conditioned power to the load while maintaining its
batteries in a charged condition. The UPS protects against the normal, everyday problems associated
with unreliable commercial power, including power sags, surges, signal interference, and spikes. This
protection keeps power-line problems from reaching your load, where they can cause equipment to operate
erratically, or damage software and hardware.
