Power-Saving Back-UPS Pro 900, 230V
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.
Battery failure notification
Provides early-warning fault analysis on batteries enabling timely preventive maintenance
Power-saving outlets
Automatically cuts power to idle equipment to conserve electricity.
Resettable circuit breaker
Easy recovery from overloads; no need to replace a fuse.
Battery-protected and surge-only outlets
Reserves power capacity and run time for connected equipment that require battery back-up while providing surge only protection for less critical equipment
Cold-start capable
Provides temporary battery power when the utility power is out.
Serial Connectivity
Use any Home Automation network to monitor and control the S20 through its RS-232 serial port. For information on how to communicate with the S20, see APC's Application Note #102. Crestron and AMX installers should visit their respective websites for information on how to integrate the S20 into those networks.
Hot-swappable batteries
Ensures clean, uninterrupted power to protected equipment while batteries are being replaced
Disconnected battery notification
Warns when a battery is not available to provide backup power.
Dataline Surge Protection
Provides protection of connected equipment from power surges on the data lines.
Automatic self-test
Periodic battery self-test ensures early detection of a battery that needs to be replaced.
Adjustable voltage-transfer points
Maximizes useful battery life by widening the input voltage window or tightening the output voltage regulation.
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 conditions.
User-replaceable batteries
Increases availability by allowing a trained user to perform upgrades and replacements of the batteries reducing Mean Time to Repair (MTTR)
USB connectivity
Provides management of the UPS via a USB port (not available on all models).
Serial Connectivity
Provides management of the UPS via a serial port.
Transformer-block spaced outlets
Protect equipment with input transformer blocks without blocking access to other receptacles.
Boost and Trim Automatic Voltage Regulation (AVR)
Gives higher application availability by correcting low and high voltage conditions without using the battery.
Intelligent battery management
Maximizes battery performance, life, and reliability through intelligent, precision charging.
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.
Building Wiring Fault Indicator
This LED informs users of potentially dangerous wiring problems in the wall circuit.
Adjustable voltage sensitivity
Provides the ability to adapt the Power Conditioner for optimal performance in specific power environments or generator applications.
Battery replacement without tools
Allows quick, easy battery replacement.
LCD graphics display
Text and mimic diagrams that display modes of operation, system parameters and alarms.
