Pure sinewave battery backup Prevents interruptions, lost pre-sets, missed DVR recordings, lost multimedia server data and premature projector bulb wear and tear when the power goes out. Boost and Trim Automatic Voltage Regulation (AVR) Eliminates voltage fluctuations as a source of AV signal degradation and component power-supply stress. Power conditioning Protects connected loads from surges, spikes, lightning, and other power disturbances. Isolated filter banks Eliminates electromagnetic and radio frequency interference (EMI/RFI) as a source of audio-video signal degradation. Dataline Surge Protection Provides protection of connected equipment from power surges on the data lines. 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. UL, FCC, CE, C-Tick approvals.

Battery replacement without tools Allows quick, easy battery replacement. Resettable circuit breakers Enables a quick recovery from overload events. Hot-swappable batteries Ensures clean, uninterrupted power to protected equipment while batteries are being replaced Multiple mounting methods Allows for standardization on one product for use in different environments. User-replaceable batteries Increases availability by allowing a trained user to perform upgrades and replacements of the batteries reducing Mean Time to Repair (MTTR) Front-access servicing Simplifies installation and maintenance while minimizing space requirements.

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. 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. Automatic self-test Periodic battery self-test ensures early detection of a battery that needs to be replaced. Intelligent battery management Maximizes battery performance, life, and reliability through intelligent, precision charging. VFD display panel Manage the UPS locally through a text-based display that allows quick diagnosis via stored alarm conditions and events. USB connectivity Provides management of the UPS via a USB port (not available on all models). Sequenced turn on/off Helps power on components in the proper order to prevent speaker stress. Proper sequencing can also help manage current draw on startup to prevent unnecessary circuit breaker tripping. LED & display dimmer Adjust the unit's LED and display brightness independently of each other to suit your individual tastes and environment.
