OVERVIEW
The APC

Back-UPS
®
CS/Back-UPS LS series of uninter-
ruptible power supplies (UPS) helps you stay connected and
protected when the power goes down.
Each model protects your PCs, monitors, printers, modems,
drives, and other peripherals from all sorts of utility-line
malfunctions that can damage or destroy sensitive equipment
and data.
Three modes of protection
All Back-UPS CS/Back-UPS LS models offer three modes
of protection: battery backup, surge protection, and phone/
fax/DSL line protection.
When a power blackout, brownout, or some other type of
interference hits your system or when utility voltage is outside
acceptable limits, the UPS automatically transfers power loads
to the battery. This gives you enough time to save valuable
work. An Unattended Shutdown feature even ensures that
files are saved and your operating system shuts down properly
in case of a sustained power outage.
Once the initial problem has been corrected, the UPS
switches power back to the primary utility power source.
Power too low? These UPSs take care of that, too.
Continuous line conditioning and automatic volt regulation
smooth out the highs and lows of power reaching your
equipment.
You can also cold-start the UPS; that is, you can start up
the Back-UPS CS/Back-UPS LS and power the loads even when
there’s no utility power provided—you use battery power
instead. This is particularly helpful when you need to access
your computer for a short time during a power outage.
Full-time surge suppression protects your equipment from
power swells and spikes from lightning strikes and other
power anomalies. In addition, full-time noise filtering prevents
data-file corruption.
The actual outlets
The Back-UPS CS/Back-UPS LS units feature a combination
of the following NEMA 5-15R outlets and an RJ-11 jack:
Battery backup outlets, which provide battery backup, surge
protection, and EMI filtering. In case of a power outage,
battery power is automatically provided to these outlets.
Power (utility or backup) isn’t supplied to these outlets when
the Back-UPS CS/ Back-UPS LS is switched off. These outlets are
ideal for connecting a computer, monitor, CD drive, or some
other device that requires uninterrupted operation.
Surge-only outlets are always on (when utility power is
available) and are not controlled by the on/off switch. Unlike
the battery backup outlets, the surge-only outlets don’t
provide power during a power outage. You use them to
connect non-data-sensitive equipment, such as a printer, fax
machine, or scanner. The surge-only outlets work without
reducing the available power or battery capacity for the
devices plugged into the battery backup ports, so you get
maximum battery power for a computer or monitor that
must be up and running at all times.
Two of the sockets on all Back-UPS CS/Back-UPS LS units
are spaced far enough apart to enable you to plug in trans-
former blocks without blocking access to the other
receptacles.
The RJ-11 telephone jack provides lightning surge
protection for any device connected to your telephone line,
whether it’s a phone, computer, modem, or fax machine. This
jack is compatible with HPNA and DSL standards, as well as
all modem data rates.
Advanced diagnostics
Use the front-panel test switch to mimic a power failure
and initiate an actual transfer to backup power. You can
also estimate battery-backup time and determine when the
battery needs to be replaced.
Audible alarms warn you of changing UPS and utility
power conditions in your application, such as when the Back-
UPS CS/Back-UPS LS is on battery, when the battery is low, or
when the connected equipment exceeds the rated load for
the UPS and, in turn, causes a power overload condition.
What’s more, a site wiring fault indictor warns you
immediately of wiring problems, like improper grounds, that
can cause shocks or prevent the the UPS from adequately
suppressing surges.
All Back-UPS CS/Back-UPS LS units feature user-replaceable
batteries too, so you don’t waste time when it comes time to
service the unit. When the Replace Battery indicator lights,
simply hot-swap an old battery with a new one—there’s no
need to repackage and send back the UPS. You can even
change batteries without powering down the connected
equipment. Microprocessor-controlled battery charging
ensures maximum battery life.
And there’s no need to return the Back-UPS CS/Back-UPS
LS to the factory because of a worn-out fuse, either. All units
have a circuit breaker instead. To reset the unit for overload
recovery, just push a button.
APC Back-UPS CS (BK350, BK500, BK500BLK)
The Back-UPS CS gives your office and home-office systems
professional-grade power protection. With the Back-UPS CS,
you can be sure that your office systems and their valuable
data don’t fall prey to dangerous power surges, spikes, and
blackouts.
