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.



Predictive replace battery date

Dynamically provides the month and year when battery replacement is recommended to aide in long term maintenance planning.



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.



Energy meter

Provides actual kilowatt hours of usage for energy conscious users.



Outlet group control

Turn on/off, reboot or shut down select outlet groups to save dispatching technicians to remote locations (for UPSs with switched outlet groups).



Sequenced shutdown and restart

Configure select outlet groups to shut down and turn on in a pre-determined order (for UPSs with switched outlet groups).



Audible alarms

Provide notification of changing flywheel conditions



InfraStruXure Central compatible

Enables centralized management via APC InfraStruXure® Central.



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.



Single switched outlet group

Single outlet group that may be controlled separately from the UPS for discrete reboot of hung devices, sequenced on/off and non-critical load shedding.



Wide input voltage range

Designed for harsh electrical environments to save battery life.



Battery failure notification

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



High online efficiency

Reduces utlility costs, generates less heat.



LED Indicators

Provide easy-to-read status of your utility power conditions, UPS and battery.



SmartSlot

Customize UPS capabilities with management cards.



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.



Automatic self-test

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



Automatic restart of loads after UPS shutdown

Automatically starts up the connected equipment upon the return of utility power.



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.



Temperature-compensated battery charging

Prolongs battery life by regulating the charge voltage according to battery temperature.



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.



Network manageable

Provides remote management of the UPS over the network.



Frequency and voltage regulation

Gives higher application availability by correcting poor frequency and voltage conditions without using the battery.



Adjustable voltage sensitivity

Provides the ability to adapt the Power Conditioner for optimal performance in specific power environments or generator applications.



Predicitive failure notification

Provides early-warning fault analysis ensuring proactive component replacement.
