APC metered-by-outlet rack power Distribution Unit (PDU) provides 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 PDU provides 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 PDU includes individual outlet power metering, a temperature/humidity sensor port, and locking IEC receptacles.
