Symmetra PX 100 kW

Scalable from 10 kW to 100 kW

Modular, scalable, high-efficiency power protection for data centers

The Schneider Electric SymmetraTM PX 100 kW is a world-class, high-efficiency, ENERGY STAR® qualified power protection system designed to cost-effectively provide redundancy and high levels of availability. Its two-rack footprint seamlessly integrates into today’s state-of-the-art data center designs. Made up of swappable power modules, battery modules, a static bypass switch, and intelligent management modules, this architecture can scale power and runtime in increments of 10 kW up to 100 kW as demand grows or when higher levels of availability are required in your data center.

Features and benefits

The Symmetra PX family serves as the core power train that drives Schneider Electric InfraStruxureTM systems for small, medium, and large data centers. Self-diagnostic capabilities enhance the manageability of the Symmetra PX 100 kW and increase overall data center reliability. Standardized, factory-assembled modules mitigate the risk of human error during installation or routine maintenance procedures. If a module requires replacement, a meantime to repair of less than 10 minutes enhances availability. Symmetra PX 100 kW fits seamlessly onto the data center floor or in the back room. In two standard Schneider Electric NetShelterTM SX racks, the Symmetra PX 100 kW delivers the high availability, extreme agility, and low total cost of ownership you have come to expect from the Symmetra PX family.

Symmetra PX 100 kW

  1. High-density footprint: With 100 kW of power protection and runtime supplied
    in the compact footprint of two standard Schneider Electric
    TM NetShelter SX racks, your load is protected by a mere 14 square feet of UPS equipment, allowing you to reclaim floor space for your IT equipment.

  2. Main intelligence module andredundant intelligence module: Backup for the swappable main intelligence module provides the maximum possible availability for your system.

  3. Swappable 10 kW high-efficiency power module: High-efficiency power modules reduce power and cooling costs, saving you money while delivering the optimal power protection your data center deserves.

  4. Dual-mains input: Dual-mains input allows for top or bottom feed connection to two separate power inputs for increased availability.

  5. Built-in static bypass switch: The swappable static bypass switch transfers the load to utility power without interruption in case of heavy overload or faulty conditions and ensures that even in 125% overload conditions, the data center remains operational.

  6. Embedded network management card: Provides UPS status and event notification to simplify UPS and power distribution unit (PDU) management. Two SmartSlotTM positions support dry contact, environmental monitoring, and building management system (modbus/Jbus) cards.

  7. LCD display interface: Offers a clear text-based overview of alarms, status data, and system configuration options in a central location.

  8. Swappable battery module: Connected in parallel for increased availability, these swappable battery modules feature advanced battery monitoring and temperature-compensated battery charging that extend battery life. Swappability lowers the cost of replacement and mean time to repair. Up to four battery frames can be installed for longer runtimes.

  9. Advanced battery management: With advanced monitoring capabilities, Symmetra PX 100 kW UPS detects failing battery units before they become a problem — no add-on battery management system necessary. Each battery unit in the battery module records its battery performance and monitors its temperature, reporting this data to the UPS. The Symmetra PX 100 also continually calculates the battery charge percentage and discharge characteristics. During utility power failure or battery self-test, the UPS performs battery diagnostics on each battery unit and generates an alarm if significant performance deviations are detected.

Best-in-class energy efficiency

Schneider Electric is proud to be the first company whose UPSs earned the ENERGY STAR — and our tradition of high-efficiency performance continues with the Symmetra PX 100 kW. Symmetra PX 100 kW is the most efficient modular UPS in its class with up to 95% efficiency, reducing your operating costs and carbon footprint, and making it the eco-conscious core of a modern data center.

The ENERGY STAR program is aimed at reducing pollutants caused by the inefficient use of energy, while also making it easy for consumers to identify and purchase the most energy-efficient products. The ENERGY STAR program distinguishes UPS systems with efficiency ratings in the top 25% of the market. Qualified
UPSs perform with excellence at 25, 50, 75, and 100% load levels, as verified by an independent certification body. By requiring consistent measurement methodology and the publication of test results, the ENERGY STAR program empowers consumers to make informed UPS comparisons.

Modular batteries: 

Modular batteries can be added or replaced quickly and easily.

  • Simply slide the battery module into place. All DC connections are preconfigured and insulated — no cable installation or contact with DC terminals required.
  • Patented rear connectors enable toolless connection and disconnection.

Parallel strings increase availability:

  • One row of modules makes one string. All battery modules support the load, so no individual battery is a single point of failure.

Now, even batteries look great in the data center.

  • No messy-looking cables — battery connections are made inside the battery unit case.
  • Fully integrated system housed in a standard IT rack form factor.

Batteries are monitored at the individual module level.

  • Each individual module monitors current, voltage, and temperature and reports the information to the UPS.
  • No time wasted — the online battery chart helps you quickly identify and replace faulty modules. See battery data that interests you and receive (configurable) alarm notifications.
