The Back-UPS RS offers high performance protection for your business and office computer systems. It provides abundant battery backup power, allowing you to work through medium and extended length power outages. It also safeguards your equipment from damaging surges and spikes that travel along utility, phone and network lines. A distinguishing feature of the Back-UPS RS is automatic voltage regulation (AVR). AVR instantly adjusts both low and high voltages to safe levels, so you can work indefinitely during brownouts and overvoltage situations, saving the battery for power outages when you need it most. Award-winning shutdown software automatically powers down your computer system in the event of an extended power outage. Additional features like audible alarms, LED status indicators, user replaceable battery, push-button circuit breakers and plentiful outlets (including transformer-block spaced outlets) make the Back-UPS RS the perfect unit to protect your business' productivity from the constant threat of power problems and lost data. <br><br>Green mode: Patent-pending operating mode that bypasses unused electrical components in good power conditions to achieve very high operating efficiency without sacrificing any protection.<br><br>Audible alarms: Provide notification of changing flywheel conditions<br><br>Battery failure notification: Provides early-warning fault analysis on batteries enabling timely preventive maintenance<br><br>Power-saving outlets: Automatically cuts power to idle equipment to conserve electricity.<br><br>LCD display: Alpha-Numeric Display which displays system parameters and alarms.<br><br>Battery-protected and surge-only outlets: Reserves power capacity and run time for connected equipment that require battery back-up while providing surge only protection for less critical equipment<br><br>Cold-start capable: Provides temporary battery power when the utility power is out.<br><br>Hot-swappable batteries: Ensures clean, uninterrupted power to protected equipment while batteries are being replaced<br><br>Automatic self-test: Periodic battery self-test ensures early detection of a battery that needs to be replaced.<br><br>Adjustable voltage sensitivity: Provides the ability to adapt the UPS for optimal performance in specific power environments or generator applications.<br><br>Audible alarms: Provides notification of changing utility power and UPS conditions.<br><br>User-replaceable batteries: Increases availability by allowing a trained user to perform upgrades and replacements of the batteries reducing Mean Time to Repair (MTTR)<br><br>USB connectivity: Provides management of the UPS via a USB port (not available on all models).<br><br>Transformer-block spaced outlets: Protect equipment with input transformer blocks without blocking access to other receptacles.<br><br>Boost and Trim Automatic Voltage Regulation (AVR): Gives higher application availability by correcting low and high voltage conditions without using the battery<br><br>Automatic Voltage Regulation (AVR): Gives higher application availability by correcting low and high voltage conditions without using the battery.<br><br>Intelligent battery management: Maximizes battery performance, life, and reliability through intelligent, precision charging.<br><br>Building Wiring Fault Indicator: This LED informs users of potentially dangerous wiring problems in the wall circuit.<br><br>
