Automatic Voltage Regulation (AVR) provides true brownout and overvoltage correction

APC Back-UPS Pro products increase your productivity by allowing you to work through problems that shut other UPSs down by automatically stepping up low voltage, and automatically stepping down high voltage to output that is safe for your computer without unnecessary battery drain.

Overvoltage puts stress on delicate computer components and causes premature failure. Brownout causes frozen keyboards and system crashes resulting in loss or corruption of data.

UPS goes on battery.
Batteries depleted; user must exit.

Back-UPS Pro continues indefinitely without draining batteries.

Back-UPS Pro units provide surge protection for a single line phone circuit or 10BT network cable to prevent "back door" damage to your computer system.

Microprocessor controlled circuitry monitors battery performance and maximizes battery life via: AVR; automatic self tests and reporting; on battery, low battery, replace battery indicators; fast battery recharging; and battery discharge protection.

An innovative design in which the inverter works "in reverse" charging the batteries during normal operation, providing greater efficiency and reliability. Outperforms standby and on-line designs.

Back-UPS Pro models have user replaceable batteries that can be easily swapped out without powering down the connected load. This saves the time and expense of returning the UPS to the factory for battery service.

Front panel LED's indicate on line, on battery, overload, and replace battery conditions; audible alarms also alert the user when the system is overloaded, on battery, has reached low battery, or needs battery replacement.

Full-time surge suppression prevents catastrophic hardware damage and extends system life. EMI/RFI filtering prevents electrical noise from affecting computer operation or introducing "glitches" into data files.

The Back-UPS Pro's site wiring fault indicator identifies potentially dangerous wiring problems before you plug in your valuable equipment.

A communication interface port on models 420 and higher provides the security of an automatic, unattended shutdown of all major operating systems, including: Windows, NT, OS/2, SCO Unix, Solaris, System 7, AIX, Lantastic, UnixWare, NetWare, and others. (PowerChute software may be required.)

If your properly connected equipment is ever damaged by an AC surge, including surges due to lightning, APC will repair or replace our product and up to $25,000 of connected equipment for as long as you own your Back-UPS Pro. (US and Canada only. See policy for details.)

UL, and CSA approvals mean a safe, reliable solution to your power problems.

Unmatched reliability means you can purchase all APC products with confidence.
