Features and Benefits
The right-sized UPS for demanding business critical applications
APC™ by Schneider Electric Symmetra™ PX 250/500 is a world-class, ultra-high efficiency power protection
system designed to cost effectively provide high levels of availability while simplifying the right-sizing of
your data center. Symmetra PX 250/500 is a true modular system consisting of hot-swappable dedicated
and redundant power, intelligence, and battery modules that facilitate easy and efficient service. This
architecture can scale power and runtime as demand grows or as higher levels of availability are required.
The Symmetra PX 250/500 systems can scale in increments of 25 kW up to 500 kW, and four systems can
be paralleled to deliver up to 2,000 kW of power protection (1.5 MW with N+1 system-level redundancy).
With industry-leading power density, the Symmetra PX has the ability to fit seamlessly onto the data
center floor or into the back room. Highly manageable, the Symmetra PX 250/500 features self-diagnostic
capabilities and standardized modules which mitigate the risk of human error. Other features include
automated predictive diagnostics, increased overload capacity, extended battery life, and on-the-fly
firmware upgrades resulting in increased overall data center reliability.
