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.
