Managed power distribution units are responsible for supplying energy and remote-control access over the individual outlets. Therefore, these units enable server restart further to monitor the energy consumption from different respective outlets. These measure frequency and voltage while allowing reporting of load power factor, both apparent and active power, while monitoring the energy consumption. These have an in-built web server that enables the unit’s remote access, thereby reading and managing the outlets of any specific PDU from the user-friendly web interface. These PDUs function using hybrid access technology with ethernet connectivity and serial communication. The PDUs remain highly compatible with the 19 inches IT racks.
