APC Symmetra PX, 20 kW / 20 kVA, Input 208V 3PH / Output 120V, 208V, 208V 3PH , Interface Port Smart-Slot , Extended runtime model , Rack Height 42 U Configurable for N+1 internal redundancy Provides high availabilty 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. 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. Audible alarms Provides notification of changing utility power and UPS conditions
