APC power distribution units with metering by outlet optimise 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, enabling data centre 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, connections for temperature and humidity sensors, locking IEC sockets, and ultra-flat circuit breakers. Configuration of the Metered by Outlet Rack PDUs is carried out via a secure web connection or SNMP or Telnet interface. Complementary management solutions include APC platforms for central management such as InfraStruxure Central, Operations, Capacity, and Energy Efficiency.
