Adjustable voltage sensitivity Provides the ability to adapt the UPS for optimal performance in specific power environments or generator applications. 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. 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 Automatic Voltage Regulation (AVR) Preserves battery life and maximizes runtime by correcting low voltages without discharging the battery. Building Wiring Fault Indicator This LED informs users of potentially dangerous wiring problems in the wall circuit. 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. Hot-swappable batteries Ensures clean, uninterrupted power to protected equipment while batteries are being replaced Intelligent battery management Maximizes battery performance, life, and reliability through intelligent, precision charging. LCD graphics display Text and mimic diagrams that display modes of operation, system parameters and alarms. Lifetime data recovery warranty Provides peace of mind by providing professional data recovery services in the event data is lost due to the failure of the unit. Resettable circuit breaker Easy recovery from overloads; no need to replace a fuse. 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. Transformer Block Spacing Connect bulky transformer block plugs without covering up other outlets. 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)
