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.
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.
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.
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.
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.
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.
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.
Ensures compatibility with different input frequencies.
Allows additional run time to be quickly added as needed.
Plug-and-Play external batteries
Ensures clean, uninterrupted power to the loads when adding extra runtime to the UPS.
Scalable power capacity
Reduces UPS over-sizing costs today by allowing quick power upgrades, within the same footprint, later.
Field-replaceable power distribution panel
Ensures compatibility with equipment that has different plug types.
Provides temporary battery power when the utility power is out.
Resettable circuit breakers
Enables a quick recovery from overload events.
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.
Ensures the product has been tested and approved to work safely with the connected service provider equipment and within the specified environment.
Ensures clean, uninterrupted power to the loads in the event of an extended power outage
Manageable external batteries
Reduces preventative maintenance service needs by monitoring the health and status of the external batteries and their expected runtime.
Alpha-Numeric Display which displays system parameters and alarms.
Customize UPS capabilities with management cards.
Intelligent battery management
Maximizes battery performance, life, and reliability through intelligent, precision charging.
Provides remote power management of the UPS over the network.
InfraStruXure Manager Compatible
Enables centralized management via the APC InfraStruXure Manager.
Disconnected battery notification
Warns when a battery is not available to provide backup power.
Actively let you know if the unit is on battery, if the battery is low or if there is an overload condition.
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)
Periodic battery self-test ensures early detection of a battery that needs to be replaced.
Predictive failure notification.
Provides early-warning fault analysis ensuring proactive component replacement.
