Features & Benefits

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.
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.
Battery modules connected in parallel: Delivers higher availability through redundant batteries.
Hot-swappable power modules: Ensures clean, uninterrupted power to protected equipment during Power Module replacement.
Hot-swappable intelligence modules: Ensures clean, uninterrupted power to protected equipment during Intelligence Module replacement.
Hot-swappable batteries: Ensures clean, uninterrupted power to protected equipment while batteries are being replaced
Modular design: Provides fast serviceability and reduced maintenance requirements via self-diagnosing, field-replaceable modules.
Network manageable: Provides remote management of the UPS over the network.
Automatic internal bypass: Supplies utility power to the connected loads in the event of a UPS overload condition or fault.

Scalable power capacity: Reduces UPS over-sizing costs today by allowing quick upgrades later.
Scalable runtime: Allows additional run time to be quickly added as needed.
Front-access servicing: Simplifies installation and maintenance while minimizing space requirements.
Programmable frequency: Ensures compatibility with different input frequencies.
SmartSlot: Customize UPS capabilities with management cards.
Battery replacement without tools: Allows quick, easy battery replacement.

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.
Automatic self-test: Periodic battery self-test ensures early detection of a battery that needs to be replaced.
Temperature-compensated battery charging: Prolongs battery life by regulating the charge voltage according to battery temperature.
Manageable external batteries: Reduces preventative maintenance service needs by monitoring the health and status of the external batteries and their expected runtime.
Intelligent Battery Management: Maximizes battery performance, life, and reliability through intelligent, precision charging.
5x8 Start-up service included:
Required for full coverage of factory warranty

InfraStruXure Central compatible: Enables centralized management via StruxureWare Central.
LED status indicators: Quickly understand unit and power status with visual indicators.
