Automatic internal bypass
Supplies utility power to the connected loads in the event of a UPS power overload or fault.

Automatic restart of loads after UPS shutdown
Automatically starts up the connected equipment upon the return of utility power.

ECO Mode
Operating mode that by-passes unused electrical components in good power conditions to achieve high operating efficiency without sacrificing protection

EPO
Attach the device to an Emergency Power Off (EPO) system so that power can be turned off in an emergency situation.

Input power factor correction
Minimizes installation costs by enabling the use of smaller generators and cabling.

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.

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.

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

Intelligent battery management
Maximizes battery performance, life, and reliability through intelligent, precision charging.

SmartSlot
Customize UPS capabilities with management cards.

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

Network manageable
Provides remote power management of the UPS over the network.

LED Indicators
Provide easy-to-read status of the unit and utility power conditions.

Serial connectivity
Provides management of the UPS via a serial port.

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

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

Predicitive failure notification
Provides early-warning fault analysis ensuring proactive component replacement.

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

Double conversion on-line topology
Guarantees a consistently high level of power quality. Any disturbances on the distribution waveform are regenerated via the zero transfer time AC to DC then DC to AC conversion process. The battery is only used as a back-up source.

ECO Mode
Operating mode that by-passes unused electrical components in good power conditions to achieve high operating efficiency without sacrificing protection

Management Software
Allows you to easily monitor your utility power and manage your UPS.

SmartSlot
Customize UPS capabilities with management cards.

Input power factor correction
Minimizes installation costs by enabling the use of smaller generators and cabling.

Generator compatible
Ensures clean, uninterrupted power to protected equipment when generator power is used.

Wide input voltage range
Designed for harsh electrical environments to save battery life.

Intuitive LCD interface
Provides clear and accurate information in multiple languages with the ability to configure the UPS locally with easy to use navigation keys.

High efficiency
High efficiency rates that remain stable even at lower operating power levels

USB connection
Use your PC to access additional power protection and management features for your UPS via a USB Port.

Allows the user to manage the UPS functions, schedule automatic shutdown and monitor the power grid occurrences through an interactive interface that ensures an easy and intuitive monitoring.
Management Software

Pure sine wave output on battery
Simulates utility power to provide the highest degree of compatibility for active PFC (power factor corrected) servers and sensitive electronics.

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.
