APC Smart-UPS Line-Interactive 9 AC outlet(s)

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.
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.
