Plug-and-Play external batteries
Ensures clean, uninterrupted power to the loads when adding extra runtime to the UPS.
Allows additional run time to be quickly added as needed.
Ensures the product has been tested and approved to work safely with the connected service provider equipment and within the specified environment.
Resettable circuit breakers
Enables a quick recovery from overload events.
Provides temporary battery power when the utility power is out.
Ensures clean, uninterrupted power to the loads in the event of an extended power outage
Protects connected loads from surges, spikes, lightning, and other power disturbances.
Frequency and voltage regulation
Gives higher application availability by correcting poor frequency and voltage conditions without using the battery.
Input power factor correction
Minimizes installation costs by enabling the use of smaller generators and cabling.
Predictive failure notification.
Provides early-warning fault analysis ensuring proactive component replacement.
Actively let you know if the unit is on battery, if the battery is low or if there is an overload condition.
Periodic battery self-test ensures early detection of a battery that needs to be replaced.
User-replaceable intelligence modules
Enables simple upgrades and replacements of the Intelligence Modules.
User-replaceable power modules
Enables simple upgrades and replacements of the Power Modules.
Increases availability by allowing a trained user to perform upgrades and replacements of the batteries reducing Mean Time to Repair (MTTR)
Disconnected battery notification
Warns when a battery is not available to provide backup power.
Provides fast serviceability and reduced maintenance requirements via self-diagnosing, field-replaceable modules.
Configurable for N+1 internal redundancy
Provides high availability through redundancy by allowing configuration with one more Power Module than is necessary to support the connected load.
Redundant Intelligence Modules
Provides higher availability to the UPS connected loads by giving redundant communication paths to critical UPS functions.
Hot-swappable intelligence modules
Ensures clean, uninterrupted power to protected equipment during Intelligence Module replacement.
Hot-swappable power modules
Ensures clean, uninterrupted power to protected equipment during Power Module replacement.
Ensures clean, uninterrupted power to protected equipment while batteries are being replaced
Power Modules connected in parallel

Battery modules connected in parallel
Delivers higher availability through redundant batteries.
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.
Peace of mind that comes with complete equipment compatibility and reliability of a market leader.
Safety agency tested and approved means that you can deploy Symmetra with confidence that they meet or exceed the industry’s most rigorous standards.
Low operating and maintenance costs with proven reliability and intelligent battery management.
Intelligent battery management, pioneered by APC, maximizes battery performance and life through intelligent, precision temperature compensated charging. Automatic self tests insure battery reliability and warn customers in advance of battery replacement. Convenient, easy to connect, hot-swappable battery modules provide battery replacement without powering down.
Save time with easy and convenient remote accessibility.
Network manageable via serial, USB or optional Ethernet. Includes Powerchute® Network Shutdown Software for convenient monitoring and control, safe operating system shutdown, and innovative energy management capabilities.
Avoids costly power problems by keeping your IT equipment and data protected and available.
Network grade power conditioning protects from damaging surges and disruptive noise. The double conversion architecture provides tight voltage regulation, frequency regulation ,and zero transfer time to battery during power events.
Modular, Scalable, Redundant Architecture future proof initial investment, improves equipment availability, and simplifies maintenance.
Symmetra LX’s redundant N+1 architecture enables the unit to withstand a failures of an intelligence module, battery or power module. Modules are easily replaceable in the field. Customers can add additional power modules or batteries after initial equipment purchase to accommodate loads of up to 16 kVA.
