The PDU technology level can vary depending on the physical location of the racks; a large hotel for instance would benefit from intelligent PDUs in racks located within the main equipment room where as individual floors within the hotel would have a lower level of intelligence required and basic metered PDUs could be installed.
There is an increasing variation of PDU configurations for different stakeholders, such as security, networks, facilities, as well as AV.
Main considerations include the level of intelligence required (basic, metered, monitored, strip level metered with outlet switching, outlet switched and outlet metering), quantity and mix of sockets, input plug types, cable length, feed input (top or bottom depending on the power feed into the cabinet being through the floor or from overhead), dual feed option, whether circuit breakers or individual fuses are required, and environmental sensors.
PDU mounting cannot be overlooked, vertical PDUs can be mounted taking up zero ‘U’ within the rack to ensure valuable hardware space is not occupied. Using mounting kits which are quick, tool-less and suitable for global branded cabinets saves engineers time and in turn company’s further installation costs.
Utilising further power management solutions, Automatic Transfer Switches (ATS) are ideal for single fed AV and network equipment and can be easily mounted into 19-inch racks.
