Audible alarms
Provides notification of changing utility power and UPS power conditions

Automatic self-test
Periodic battery self-test ensures early detection of a battery that needs to be replaced.

Automatic Voltage Regulation (AVR)
Automatically steps up low voltage and steps down high voltage to levels that are suitable for your equipment.

Battery failure notification
Provides early-warning fault analysis on batteries enabling timely preventive maintenance

Battery replacement without tools
Enables fast battery replacement, lowering Mean Time to Repair (MTTR).

Battery-protected and surge-only outlets
Reserves power capacity and run time for connected equipment that require UPS battery back-up while providing surge only protection for less critical equipment

Boost and Trim Automatic Voltage Regulation (AVR)
Gives higher application availability by correcting low and high voltage conditions without using the battery (not available on all models).

Cold-start capable
Provides temporary battery power when the utility power is out.

Dataline surge protection
Provides protection of connected equipment from power surges on the data lines.

Disconnected battery notification
Warns when a battery is not available to provide backup power.

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.

Hot-swappable batteries
Ensures clean, uninterrupted power to protected equipment while batteries are being replaced

LCD graphics display
Text and mimic diagrams that display modes of operation, system parameters and alarms.

Power-saving outlets
Automatically cuts power to idle equipment to conserve electricity.

Safety-agency approved
Ensures the product has been tested and approved to work safely with the connected service provider equipment and within the specified environment.

USB connectivity
Provides management of the UPS via a USB port (not available on all models).

User-replaceable batteries
Increases availability by allowing a trained user to perform upgrades and replacements of the batteries reducing Mean Time to Repair (MTTR)
