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. Multiple UPSs can be installed in parallel for ultra-efficient system redundancy or up to 2MW of power protection. Parallel installations with custom switchgear and installations using a 3rd-party maintenance bypass panel require the APC Symmetra PX250/500 Third Party Switchgear Kit for breaker monitoring and EPO functionality.
Includes: Assembly service, Installation guide, Network management card, Start-up service, User manual
Dual mains input
Increases availability by allowing the UPS to be connected to two separate power sources.
Operating mode that by-passes unused electrical components in good power conditions to achieve high operating efficiency without sacrificing protection
Simplifies installation and UPS maintenance while minimizing space requirements.
LCD graphics touch screen display
Full color text and mimic diagrams that easily display modes of operation, systems parameters and alarms.
During maintenance procedures, maintain full protection by transferring the load from one independent Symmetra PX 250/500kW system to another.
Output synchronization to external source
UPS systems can be synchronized with any other independent source for use with downstream static transfer switches.
Increases total power capacity by using multiple uninterruptible power supplies simultaneously.
Increases the overall system availability, 2 units running in parallel with active load sharing.
Download the display interface to your laptop or personal computer. Remotely monitor the UPS and configure a sub-set of UPS parameters. Note: Remote start-up and shutdown are not supported.
Supports 3rd party maintenance bypass
The APC Symmetra PX250/500 Third Party Switchgear Kit is required for installations with custom switchgear or a 3rd-party maintenance bypass panel. The boards in this kit monitor the breakers and provide EPO functionality.
Symmetra PX Features & Benefits
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.
Ensures clean, uninterrupted power to protected equipment when generator power is used.
Input Power Factor Correction
Minimizes installation costs by enabling the use of smaller generators and cabling.
5x8 Start-up service included
Required for full coverage of factory warranty
Provides scalability, N+1 redundancy, fast serviceability, and reduced maintenance requirements via self-diagnosing, hot-swappable, and field-replaceable modules.
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.
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.
Swappable power modules
Allows quick addition of power capacity or replacement of existing power modules. Installed modules are automatically recognized by the system.
Redundant Intelligence Modules
Provides higher availability to the UPS connected 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.
Scalable power capacity
Reduces UPS over-sizing costs today by allowing quick power upgrades, within the same footprint, later.
Ensures compatibility with different input frequencies.
Customize UPS capabilities with management cards.
Provides notification of changing utility power and UPS power conditions
LED status indicators
Quickly understand unit and power status with visual indicators.
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 environments from anywhere on the network
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)
Battery modules connected in parallel
Delivers higher availability through redundant batteries.
EU CoC for UPS
Ensures that UPSs sold in the EU are highly efficient
