APC power distribution units with metering by outlet optimize energy usage and protect circuits by capturing 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, 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 feature numerous functions and characteristics: monitoring of active power, connection for temperature/humidity sensors, locking IEC outlets, 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. Complementary management solutions include APC platforms for centralized management such as InfraStruxure Central, Operations, Capacity, and Energy Efficiency.
