Back-UPS Office Features & Benefits


USB compatible
USB 2.0 compatibility and connectivity ensures quick and easy installation of the free file-saving, auto-shutdown software.
Transformer Block Spacing
Designed to allow the use of up to two transformer block plugs without blocking access to other receptacles.
User-replaceable batteries
Save time and money by swapping the battery yourself. There is no need to send the unit to a factory service center.
User-Renewable UPS System
With normal use, a UPS battery will last three to six years. APC’s renewable UPS system eliminates the need for factory service and loss of protection by letting you replace batteries for a fraction of the cost of a new UPS.
Automatic self-test
Biweekly testing of all internal components, including the battery, ensures your unit is ready when you need it.
You can power on the unit without any input power. This provides temporary emergency battery power when the utility power is out.
Intelligent battery management
Maximizes battery performance, life and reliability with microprocessor-controlled intelligent battery management.


Lightning and Surge Protection
Protection from surges, spikes and even lightning is guaranteed!
Multipath Protection
With dedicated outlets for computer, monitor and peripherals everything is safe from the threat of bad power.
Resettable circuit breaker
Instead of a hard to find fuse, there is a push-button circuit breaker for easy recovery from an overload or short circuit.
Unattended Shutdown
This ensures that files are saved and the Operating System is properly shutdown in the event of a sustained power outage.
File-saving, auto-shutdown software for Windows 98/Me/XP/2000 and Mac OS 9 (9.0.4 or higher)
Site wiring fault indicator

Internet FAX - modem - DSL protection
Protects system from surges traveling on a phone, fax or modem line.
