APC power distribution units with metering by outlet optimize energy usage and protect circuits by collecting measurement data at each outlet. Real-time remote monitoring of connected loads is made possible through current measurements. Metered by Outlet Rack PDUs provide data on energy consumption, enabling data center managers to make informed decisions about load distribution and proper sizing of IT environments, thereby reducing overall operating costs. The devices come with numerous features and characteristics: monitoring of active power, connections for temperature/humidity sensors, locking IEC sockets, and ultra-flat circuit breakers. Configuration of the Metered by Outlet Rack PDUs is done via a secure web connection or SNMP or Telnet interface. Additional management solutions include APC platforms for centralized management such as InfraStruxure Central, Operations, Capacity, and Energy Efficiency.
