APC power distribution units with measurement functionality per outlet ensure optimization of energy usage and protection of circuits through measurement data collection 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, allowing data center managers to make informed decisions about load distribution and the proper sizing of IT environments, thereby reducing overall operating costs. The devices come with numerous features and characteristics: monitoring of active power, connection for temperature and humidity sensors, IEC sockets with locking mechanisms, and ultra-flat circuit breakers. The configuration of the Metered by Outlet Rack PDUs is done via a secure web connection or SNMP or Telnet interface. Complementary management solutions include APC platforms for centralized management such as InfraStruxure Central, Operations, Capacity, and Energy Efficiency.
