APC Metered-by-outlet Rack Power Distribution Units (PDUs) provide active metering of individual outlets to enable energy optimization and detailed capacity planning. User-defined alarm thresholds mitigate risk with real-time local and remote alerts to warn of potential circuit overloads. Metered-by-outlet rack PDUs provide a more granular level of power utilization data to allow Data Center Managers to make more precise decisions on load balancing and right sizing IT environments to lower total cost of ownership. Metered-by-outlet Rack PDUs include individual outlet power metering, a temperature/humidity sensor port, and locking IEC receptacles. Users can access and configure Metered-by-outlet rack PDUs through secure Web, SNMP, or Telnet Interfaces and are complimented by APC Centralized Management platforms using StruxureWare Data Center Expert, Capacity Manager and Change Manager.
