APC Symmetra PX 250/500 kW UPS

A high-performance, 3-phase, modular, scalable, power protection solution with industry-leading efficiency, capacity, and performance for medium to large data centers and mission critical environments.

Sym PX Efficiency



SY250K250F Features

Swappable batteries: Allows quick addition of runtime capacity or replacement of existing battery modules

Mega Tie: Maintain full protection by transferring the load from one independent Symmetra PX 250/500kW system to another

Remote Display: Remotely monitor the UPS and configure a sub-set of parameters. Remote start-up and shutdown (not supported)

Battery replacement without tools: Enables fast battery replacement, lowering Mean Time to Repair (MTTR)

ECO Mode: By-passes unused electrical components to achieve high operating efficiency without sacrificing protection

LCD graphics touch screen display: Full color text and mimic diagrams that easily display modes of operation, systems parameters and alarms

Output synchronization to external source: UPS systems can be synchronized with any other independent source for use with downstream static transfer switches

Dual mains input: Increases availability by allowing the UPS to be connected to two separate power sources

Scalable runtime: Allows additional run time to be quickly added as needed

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

Battery modules connected in parallel: Delivers higher availability through redundant batteries

Front-access servicing: Simplifies installation and UPS maintenance while minimizing space requirements

Parallel-capacity capable: Increases total power capacity by using multiple uninterruptible power supplies simultaneously

Parallel-redundant capable: Power the connected equipment with multiple uninterruptible power supplies to increase system redundancy

Manageable external batteries: Reduces preventative maintenance service needs by monitoring the health and status of the external batteries

Battery failure notification: Provides early-warning fault analysis on batteries enabling timely preventive maintenance

Temperature-compensated battery charging: Prolongs battery life by regulating the charge voltage according to battery temperature

Intelligent battery management: Maximizes battery performance, life, and reliability through intelligent, precision charging

Symmetra PX Features & Benefits


Configurable for N+1 internal redundancy: Provides high availability through redundancy additional power modules equally share load

Redundant Intelligence Modules: Provides higher availability to the UPS loads by giving redundant communication paths to critical UPS functions

Power Modules connected in parallel: Enhances availability by allowing immediate, seamless recovery from isolated module failures

Swappable power modules (Hot online swap): Allows quick addition of power capacity or replacement of existing power modules Installed modules are automatically recognized by the system

Modular design: Provides fast serviceability and reduced maintenance requirements via self-diagnosing, field-replaceable modules

Network manageable: Provides remote power management of the UPS over the network

Automatic internal bypass: Supplies utility power to the connected loads in the event of a UPS power overload or fault


Scalable power capacity: Reduces UPS over-sizing costs today by allowing quick power upgrades, within the same footprint, later

Programmable frequency: Ensures compatibility with different input frequencies

SmartSlot: Customize UPS capabilities with management cards

Total Cost of Ownership

Fully-rated power kVA equals kW: Reduces cost by eliminating the need for an oversized UPS for Power Factor Corrected (PFC) loads

Input power factor correction: Minimizes installation costs by enabling the use of smaller generators and cabling

Generator compatible: Ensures clean, uninterrupted power to protected equipment when generator power is used

5×8 Start-up service included: Required for full coverage of factory warranty


Integrates with StruxureWare Data Center Expert: An IT-ready, scalable access monitoring system that collects, organizes, and distributes critical alerts, surveillance video and key information, providing a unified view of complex physical infrastructure from anywhere on the network

LED status indicators: Quickly understand unit and power status with visual indicators

Audible alarms: Provides notification of changing utility power and UPS power conditions
