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.
